Staining of cells TableView (new)

Here is another question from staining of cells with a different plug.

You have a TableView with three columns - category, inside and out. You add a blank line and then you start to edit the category column. When you have added a category you want to see a change in the color of the other cells two columns in the same row as the value of the category.

Say if the category is "income" then the cell 'In' will become green and the 'Out' cell becomes red. The important point here is that these cells and the underlying domain object has not all the values associated with these columns again. The cells are empty and color change is to show the user where the value must be set for the category concerned (in the green cell ).

After that the category value is committed a 'message' must therefore being propagated in the category for the current line (or the entire table) column to extricate himself. I tried to call the following methods of method 'commit()' of the category column, but none of them does raise a repaint:

-getTableRow () .requestLayout ();

-getTableRow (.updateTableView) (getTableView ())

-getTableRow (.updateIndex) (getTableView () .selectionModelProperty () .get () .selectedIndexProperty () .get ());

Any suggestion of work would be more then welcomed.

Once paint it is triggered then incoming and outgoing of cells in a table column can take the current value of the underlying domain object category (say MyRecord) like this

Registration of MyRecord = getTableView () .getItems () .get (getTableRow () .getIndex ());

String category = row.getCategory ();

and call the setStyle ("...") on the cell to change the color.

Isn't time for a complete example now, but a strategy is:

Set a rowFactory on the table view that returns a table row that falls into the category for its corresponding article. Update the class style (in JavaFX 2.2) or a State of alright (in Java 8) for the row in the table according to the category.

Define a factory of cells for columns that statically defines a class on cells (for example 'in' and 'out').

Use an external style sheet that looks like this:

.table-row-cell.income .table-cell.in, .table-row-cell.expenditure .table-cell.out {
-fx-background-color: green ;
}

.table-row-cell.income .table-cell.out, .table-row-cell.expenditure .table-cell.in {
-fx-background-color: red ;
}

Here is an example of a row of table factory that manipulates the class style of the table cell. There is a link to a version that uses Java 8 alright States, that is much cleaner.

Cell TableView coloring on updates - realizing if sort happened

I'm doing has highlighted cells (in color) in a TableView whenever they are updated. My solution is based on the implementation of cell factories and use Animation (mounting) control cell background opacity - it works very well: whenever a cell value is updated, the background changes color, then fades away well.

The problem is, that if the table is sorted by clicking a column header, the underlying list is changed (of course), and the GUI level, it is also understood as a change and depending on the circumstances by cell (I flash a cell if its new value is different from the previous), several cells show an update unnecessarily (flashing).

I wonder how I could eliminate if a cell has been updated due to a 'real' update (an element has been updated) of the case when the list sort column and/or the order has been changed? I thought to catch the event of sorting (by adding an InvalidationListener to the sort order list) and ignore the updates, while it is underway, but I can't really know when it's over. I bet at the GUI level, there is no way to determine the reason, so I need a deeper understanding...

Thanks for the tips.

Register a listener for change with the appropriate property to change the highlight color for the cell according to the case. You need to do a bit of work to make sure that the listener is registered and non-registered as appropriate that the cell is reused for the different table elements: the trick is to use

Bindings.Select (tableRowProperty (), "point")

to get an observable of the current value of the line.

Update:

Well, the previous example did not work. For reasons I can't understand, after sorting (or scroll, in fact), the evil cell became the property change notifications.

So here's another strategy: keep track of the last known value of the cell line, and don't make the highlight is still called same rank value after the update. I prefer kind of the strategy described above, but I couldn't make it work.

TableView containing the format of table TextFieldTableCells

Hello

I have a TableView consisting of columns of TextFieldTableCells and I would format a cell based on another cell in the same row value. As the CellFactory is fixed for each of the TableColumns use a TextFieldTableCell.forColumn (), how can I optimize both the cell formatting and access to the row in the same call updateItem object?

IM really stuck thereby and would appreciate pointers.

See you soon

Andy

It has much in common with the cell TableView coloring updates - realizing if sort arrived: you might want to take a look at the response to this first.

How can I get both the cell formatting

TextFieldTableCell subclass and override the updateItem() method to do the formatting. If you format conditionally other properties (for example other columns) which can change, you will need to listen to these properties for changes. You must handle the listener carefully that the cell can be reused for different elements in the table. This part is similar to the above thread.

and access to the line in the same call updateItem object

Use getTableRow () .getItem () to access the value of the row in the table. You can also use table.getItems () .get (getIndex). Both methods require audits: getTableRow() does not return null, which the getIndex() return a value in the range.

I think you should start by defining your model; simply copy the class Person here is obviously not going to work. It is difficult to incorporate the ComobBox until you have data to define this option is selected. Once you have defined your data model, which is a class whose instances represent each row in the table, then it should be much easier to understand how to write the updateItem (...) method.

Anyone can focus a TableView element properly?

Run the following code:

It's a simple TableView... now, try without clicking with the mouse or by using the cursor keys to navigate this TableView using nothing more than the page - up and page-down keys. It does not work. After you select an item with the mouse, or navigate once with the cursor, THEN pg-up/page-down keys work also.

How can I fix these keys work early?

Select any line by program. Add the following line:

an alphabet by typing in a cell gives drop down suggestions from previous hits on the same column. But how the drop down to choose the suggestions of the other columns and other sheets.

Hi mdsavol,

Your observations are accurate. The 'suggestions' are previous entries in the same column that correspond to what has been entered so far in the active cell. The only direct user control is to activate the function turn on or off in numbers preferences > general.

There are other ways to include or exclude items of suggestions:
- To remove typos in the suggestions list, the user must correct the typos in the cell above the active cell. If they are more in the list, they won't be presented as suggestions.
- To include selections added to the list, the user must enter these suggestions in the individual cells above the active cell and column where they are wanted as suggestions.
There was a request here a while there is a list of suggestion 'live' similar to those of some websites, which offers a descending list of possible entries as a type in an input box.

The only way I see to reach a solution similar to what you have asked is to use as many lines at the top of the non-en-tete of the table section to list the items likely to repeat in your table, and then hide the lines. You'll need a list for each column where you want to use this feature with a list previously planted. Existing items will then require a likely hit up to three, then a click to choose from a list small enough to enter a value into a cell. News he will need to enter in full the first time, but after that it will be put on the list and answer the same thing as the terms preseeded.

While your setting upward (or decide not to do), consider going on the menu of number (in numbers), choosing to provide feedback from numbers and writing a feature in Apple request. Describe what you want. Explain how he could help the average user numbers, and then hope for the best.

Kind regards

Creating a TableView with a component, problem with my lines.

I am trying to create a table in a pane. Each row in the table will have three columns. I found an example of code to create the table, but I'm getting additional lines that I don't want.

I want only lines with 3 columns but I have extra lines, including the content of the last column see image.

Is someone can you please tell me what is wrong with my code?

    private Pane createPane(String category) {

        VerticalFieldManager vfm = new VerticalFieldManager();

        vfm.add(new LabelField("Add Task:", Field.FOCUSABLE | LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH));

        // Initialize the model if it has not yet been loaded
        _tableModel = new SortedTableModel(StringComparator.getInstance(true), 2);

        // Populate the list
        for (int i = 0; i < 3; i++) {

            String col1 = i + " 1";
            String col2 = i + " 5";
            String col3 = i + " 3";

            _tableModel.addRow(new Object[]  {col1, col2, col3});
        }

        RegionStyles style = new RegionStyles(BorderFactory.createSimpleBorder(new XYEdges(1, 1, 1, 1), Border.STYLE_SOLID), null, null,
            null, RegionStyles.ALIGN_LEFT, RegionStyles.ALIGN_TOP);

        // Create the view and controller
        TableView tableView = new TableView(_tableModel);
        TableController tableController = new TableController(_tableModel, tableView);

        // Set the controller focus policy to highlight rows
        tableController.setFocusPolicy(TableController.ROW_FOCUS);

        // Set the behaviour of the controller when a table item is clicked
        tableController.setCommand(new CommandHandler()
        {
            /**
             * @see CommandHandler#execute(ReadOnlyCommandMetadata, Object)
             */
            public void execute(ReadOnlyCommandMetadata metadata, Object context)

                fields[2] = new LabelField(data[2], Field.FOCUSABLE);

                return fields;
            }
        };

        // Set up regions
        dataTemplate.createRegion(new XYRect(0, 0, 1, 1), style);
        dataTemplate.createRegion(new XYRect(1, 0, 1, 1), style);
        dataTemplate.createRegion(new XYRect(2, 0, 1, 1), style);

        // Specify the size of each column by percentage, and the height of a row
        dataTemplate.setColumnProperties(0, new TemplateColumnProperties(15, TemplateColumnProperties.PERCENTAGE_WIDTH));

        dataTemplate.setColumnProperties(2, new TemplateColumnProperties(70, TemplateColumnProperties.PERCENTAGE_WIDTH));
        dataTemplate.setRowProperties(0, new TemplateRowProperties(ROW_HEIGHT));

        // Apply the template to the view
        tableView.setDataTemplate(dataTemplate);
        dataTemplate.useFixedHeight(true);

        vfm.add(tableView);

        // Pane's title
        LabelField iconTextLabelField = new LabelField(category, Field.FOCUSABLE | Field.FIELD_HCENTER);
        return (new Pane(iconTextLabelField, vfm));
    }

Thanks in advance.

 _tableModel = new SortedTableModel(StringComparator.getInstance(true), 2); <-- "2" sorts it by the object at index 2, which is your "col3". The extra rows you see are like headers for the sorting. I think you should use a different Table Model.

        // Populate the list
        for (int i = 0; i < 3; i++) {

            String col1 = i + " 1";
            String col2 = i + " 5";
            String col3 = i + " 3";

            _tableModel.addRow(new Object[]  {col1, col2, col3});
        }

Find/replace style cell with GREP

Hi all, (my first post here)
I found a script very useful on this forum to find/replace cell styles in an array. I adapted the script using Peter Kahrel ebook for use with a GREP query.
I've linked to a spreadsheet in InDesign CC 2014 I want to highlight the cell of new products that contain the value [Y].
When I run the script below, I get random results.
myDoc = app.activeDocument var
app.findGrepPreferences = app.changeGrepPreferences = null
app.findGrepPreferences.findWhat = "\[\u\"]
var myFound = myDoc.findGrep)
for (i = 0; i < myFound.length; i ++)
{
If (. parent.constructor.name myFound [i] == "Cell")
{
. parent.appliedCellStyle myFound [i] = "New_Product_Cell".
}
}

Modify the script that I wrote above.

Otherwise your discovery is just '[u]' ==> multi-ad found is--> Direct manufacturer name

new positioning

Hi guys,.

Please check the code below

 public VBox getVBox() {
        VBox myBox = new VBox();
        myBox.setSpacing(20);
        myBox.setLayoutX(20);
        myBox.setLayoutY(20);
      

        TableView<Person> tableView = new TableView<Person>();
        TableColumn firstNameCol = new TableColumn("First Name");
        firstNameCol.setProperty(firstName);
        firstNameCol.setMaxWidth(100);
        

        TableColumn lastNameCol = new TableColumn("Last Name");
        lastNameCol.setProperty(lastName);
        lastNameCol.setMaxWidth(100);

        TableColumn cityNameCol = new TableColumn("city");
        cityNameCol.setProperty(addName);
        cityNameCol.setMaxWidth(100);

        TableColumn addNameCol = new TableColumn("Address");
        addNameCol.setMaxWidth(100);
        addNameCol.setProperty(cityName);

        TableColumn postNameCol = new TableColumn("PostCode");
        TableColumn notesNameCol = new TableColumn("Street");
        TableColumn tableNameCol = new TableColumn("Notes");
        tableView.getColumns().addAll(firstNameCol, lastNameCol, cityNameCol, addNameCol, postNameCol, notesNameCol, tableNameCol);
        myBox.getChildren().addAll(tableView);
        return myBox;

    }

The person object is composed of various getter, setter methods and get the full result of database. But how to assign them to the corresponding columns of the table? any example sample to provide data in the table?
Thanks in advance.

How to use CheckBoxTableCell

Hi all

I would like to have editable box in a table.

That's what I have now.

TableColumn selectCol = new TableColumn ("Select");
selectCol.setEditable (true);
() selectCol.setCellValueFactory
new PropertyValueFactory < OrderCheck, Boolean >("selected"));
selectCol.setCellFactory (CheckBoxTableCell.forTableColumn (selectCol));

Questions
(1) it still shows the box unchecked regardless of the "selected" in the object value
(2) how does the 'selected' value has updated after checkbox is selected or deselected?

Thank you.

Published by: ericC on 27 December 2012 22:06

Assuming that the property selected in the OrderCheck class is a ObservableValue (for example, a BooleanProperty), I think that your code should work. Updates occur when selected the checkbox property is bound in both directions to the property "selected" in your class (passing in the selectCol to the CheckBoxTableCell.forTableColumn method).

This example works for me:

        new Person("Neil", "Young"),
        new Person("Willie", "Nelson"),
        new Person("Natalie", "Merchant")
    ));
    tableView.getItems().get(3).setVegetarian(true);

Is no longer possible to publish a stream in iTunes you and in the podcast store

Just a heads up-

We spent several years some of our streams iTunes U published in the regular iTunes podcast store often use the same RSS feed for both. Since the recent launch of iTunes Connect (the new quote and service management of content from the iTunes store), however, it seems that it is possible to submit an RSS feed in iTunes you and the iTunes podcast store. I get a message that says "status: Validation failure ' and 'cannot submit your feed. Your feed had already been submitted. »

I submitted a ticket to Apple support, but some trial and error tests suggests that there is a workaround. If you have already submitted your feed to iTunes U, you can submit it to the iTunes podcast store but you need to replace the feed URL and the title of the podcast. I don't know if cela a new policy from Apple or a glitch in the new iTunes Connect service.

Another work around could be to send the stream to the podcast to iTunes store first and then submit to iTunes U public site manager using-, but I have tested this theory yet.

Hi Tom,

As I KNOW you're not supposed to do this in the first place. (It's what we were told in 2009).

I guess Apple is simply start applying this restriction.

Best, Erik

Someone please send me an example how to implement the sublayout method

       }*/

       while(refdata.hasMoreTokens())
       {
           String temp = refdata.nextToken().trim();
           String pressure = refdata.nextToken().trim();
           Object[] row = {temp, pressure};
           _tableModel.addRow(row);          

       }
       TableView tableView = new TableView(_tableModel);
       tableView.setDataTemplateFocus(BackgroundFactory.createLinearGradientBackground(Color.PURPLE, Color.PINK, Color.YELLOW, Color.RED));
       TableController tableController = new TableController(_tableModel, tableView);
       tableController.setFocusPolicy(TableController.ROW_FOCUS);
       tableView.setController(tableController);

       DataTemplate dataTemplate = new DataTemplate(tableView, NUM_ROWS, NUM_COLUMNS)

       };

       dataTemplate.useFixedHeight(false);

       // Define regions and row height
       dataTemplate.setRowProperties(0, new TemplateRowProperties(ROW_HEIGHT));
       for(int k = 0; k < NUM_COLUMNS; k++)
       {
           dataTemplate.createRegion(new XYRect(k,0,1,1));
           dataTemplate.setColumnProperties(k, new TemplateColumnProperties(Display.getWidth()/NUM_COLUMNS));

       // Apply the template to the view

       tableView.setDataTemplate(dataTemplate);
       vfm.add(tableView);
       filteredList.addDataSet(0, temperature, "Temperature", BasicFilteredList.COMPARISON_IGNORE_CASE);         

       // Create AutoCompleteFields

       AutoCompleteField autoCompleteField = new AutoCompleteField(filteredList, AutoCompleteField.LIST_STATIC | AutoCompleteField.LIST_DROPDOWN);

       // Add the AutoCompleteFields to the screen           

       //add(new LabelField("Choose a Value"));
       vfm.add(autoCompleteField);

   }

In my application I am stretching from Verticalmanager to my class and display data in tableview.

but the problem is that all the data is displayed with the scroll bar. To get the scroll for the tableview bar

I sends you only (code tableview) if someone meets me, I want to paste all of the code.

Please answer

Please stand to be corrected if I'm wrong, you want to set the height of a manager who is unscrollable, in a Manager, a list field must be added, which is scrollable. First make the screen unscrollable by great call (Manager.No_VERTICAL_SCROLL); Then create a handler, override its methods getPreferredWidth(), getPreferredHeight() and sublayout(), as below:

mainManager = new VerticalFieldManager(Manager.VERTICAL_SCROLL){
            public int getPreferredWidth()
            {
                return super.getPreferredWidth();
            }
            public int getPreferredHeight()
            {
                                // fixed height
                return height;
            }
            protected void sublayout( int maxWidth, int maxHeight )
            {
                super.sublayout(getPreferredWidth(),getPreferredHeight());
                setExtent(getPreferredWidth(),getPreferredHeight());
            }
        };

mainmanager add to your list.

The demo "big grid" is obsolete and has been replaced by SXSSF, which is compatible with XSSF (seehttp://poi.apache.org/spreadsheet/how-to.html#sxssf the new Halloween Document) API.

Theoretically, all you need to do is replace "new XSSFWorkbook()" by "new org.apache.poi.xssf.streaming.SXSSFWorkbook ()" in your program.

You better post any specific questions of POI on the forum of the user Apache POI (see mailing lists , Apache POI)

Import/coupling of spreadsheet calculation + updated data in the form

This is an import/formatting of the data that I'm working on. http://imgur.com/a/fr0C1 [1]
When I sections are looking exactly how I would like it, I'm creating table styles, cell and new paragraph. When the linked spreadsheet is updated it loses formatting. When I reapply all styles, he will eventually justify the Centre 2 data columns to the right, rather than centered & left.
Thanks for the idea!

Answered in another forum:

ElectricCharlie

To do this, I'll make sure that your table style specifies "[None]" to all of your cell styles. I create a cell for each column style and create the corresponding paragraph for each paragraph style styles. Within each cell style, specify the desired paragraph style. (This should tumble down the styles correctly.)

I don't directly apply paragraph for text styles, because that can be reset to re - import. And I'll make sure that in your desired result, that there is no overridden style. Substitutions might be getting dropped when you change the text.

I have not mocked this scenario on my end, but I think it will solve the problem.

LifeDrive

According to your instructions for the error (error Sys0505) (0.841), I deleted the following files of my LifeDrive: MY PALM ACCOUNT; MY HEEL PALM BEAM; MY TREO ACCOUNT; AND MY TREO SYNC. However, when I sync with the "office crush unit", these files reappear. When I sync once more with the "device replaces the office", I can not sync at all. By the way, this am I ordered a Palm Treo 800W from Sprint and I'm worried that I might have the same questions cela this new device.

The best way is to delete these files again and go to start my computer C:------drive - program files and look for Palm or PalmSource. Then look for the name of your profile and rename the backup folder Backup.Old

When you hotsync, none of the items in the backup folder will be synchronized to your handheld.
