There are different ways to do
eg.:
in your container of ListItem:
background: ListItem.selected || ListItem.active ? Color.Magenta : Color.Transparent
in your onTriggered of the ListView:
// select line
myListView.select(indexPath, true)
Remember, if your work has been done:
// clear the selection
myListView.clearSelection()

How do I set the background / highlight on the listView when select multi use
Hi, I'm used to select multi on the list view, the problem is when the selected item does not change the background (I think by default will change in light blue)
Maybe because I'm not using StandardListItem on itemList, I use clean container for itemList.
How to set the color to the element highlighted on multi select listView?
Thank you
I use the background property on my customized itemList:
{Of container
ID: listItemContainer

How to refresh the Listview after adding a new item
Hello
I have the following list:
ListView { id: channelsList dataModel: categoryModel listItemComponents: [ ListItemComponent { type: "item" StandardListItem { title: ListItemData.name // Channel name imageSource: ListItemData.imageFile status: ListItemData.id id: channelItemId contextActions: [ ActionSet { //title: contentView.title ActionItem { title: "Add to Favorites" onTriggered: { console.log(ListItemData.id + " will be added to the Favorites"); //categoryModel.addFavorite(ListItemData.name, ListItemData.imageFile, ListItemData.id); channelItemId.ListItem.view.viewTriggered(ListItemData.name, ListItemData.imageFile, ListItemData.id); } } } ] } } ] onTriggered: { var chosenChannel = dataModel.data(indexPath); console.log("indexPath: " + indexPath); var playingPage = playpagedef.createObject(); playingPage.chname = chosenChannel.name; playingPage.cid = chosenChannel.id; playingPage.init(); Qt.nav.push(playingPage); } attachedObjects: [ // The bucket categoryModel is a non visible object so it is set up as an attached object. // The categoryModel itself is a QListDataModel defined in categorymodel.h and registered // as a type in the creation of the application. CategoryModel { id: categoryModel // The path to the JSON file with initial data, this file will be moved to // the data folder on the first launch of the application (in order to // be able to get write access). jsonAssetPath: "models/channels.json" // The filtering is initially set to "Category 1" to show category channels filter: label.text }, ComponentDefinition { id: playpagedef source: "PlayingPage.qml" } ] function viewTriggered(name, imageFile, id) { categoryModel.addFavorite(name, imageFile, id); categoryModel.clear(); } }and the categoeymodel.h is as follows:
#ifndef _CATEGORYMODEL_H #define _CATEGORYMODEL_H #include
#include #include #include using namespace bb::data; // The category categoryModel is based on the QListDataModel template, which in turn // implements the abstract DataModel class. typedef bb::cascades::QListDataModel CategoryListModel; /* CategoryModel Description: * * CategoryModel class for the Category List application, the data categoryModel * reads and write from a JSON file that keeps all item data * for the list. */ class CategoryModel: public CategoryListModel { Q_OBJECT Q_PROPERTY(QString filter READ filter WRITE setFilter NOTIFY filterChanged) Q_PROPERTY(QString jsonAssetPath READ jsonAssetPath WRITE setJsonAssetPath NOTIFY jsonAssetPathChanged) public: /** * Constructor that sets up the recipe * @param parent The parent Container, if not specified, 0 is used */ CategoryModel(QObject *parent = 0); ~CategoryModel(); QString filter(); void setFilter(const QString filter); QString jsonAssetPath(); void setJsonAssetPath(const QString jsonAssetPath); signals: void filterChanged(QString filter); void jsonAssetPathChanged(QString jsonAssetPath); public slots: void addFavorite(QString channelName, QString channelImageFile, int channelId); private: bool jsonToDataFolder(); // Property variables QString mFilter; QString mJsonAssetsPath; QString mJsonDataPath; // A list containing all data read from the JSON file QVariantList mData; //Invocation variables bb::cascades::Invocation* mInvocation; }; #endif // ifndef _CATEGORYMODEL_H My problem is that the listview is not get automatically updated when a new item is added to the datamodel (a favorite channel is added). I have to exit the application and restart to see the updated list.
categoryModel.addFavorite(name, imageFile, id); categoryModel.clear();
categoryModel.clear ();
does not work. I get:
Asset: / / / hand. QML:180: TypeError: result of expression 'categoryModel.clear' [undefined] is not a function.
I would like to know how to achieve using approach "more correct".
QListDataModel does not expose its internal storage directly. It is possible to reconstruct the map by performing an iteration in a loop (with the help of data() and size() methods), the dataModel entries:
http://developer.BlackBerry.com/Cascades/reference/bb__cascades__qlistdatamodel.html
but I don't see how this could help. If the filtered data is changed, it must be merged with the original sort data.
Why the original approach has not worked?
I could not understand from the description appearance of the interface user, please post a screenshot if possible.

How can I add an item to the ListView
I have a very basic question. I would like to read data from a file xml in the ListView, then add an item to the list and store it in the file xml again. How can I do?
{To ListView
ID: listViewCustomUrl
objectName: "listViewCustom."
dataModel: {XmlDataModel}
Source: "dataCustom.xml".
}
}
First of all, your xml file must be in a read/write file in your directory app, say data, for example.
Then, you can use a DataModel in memory (GroupDatModel), fill it with XMLcontents, a number of updates for this model, and then when your output or with an option to be persisted in the xml file.
See the example of persistent objects in http://blackberry.github.io/Cascades-Samples/persistentobjects.html

Change the image, click the Listview item
Hi all
I want to change the image of the listview element. When I touch on the element of the list the image is modified and after leave the key event the modified image remains same. Please solve my problem.
Thank you & best regards
Sanjit
remove the other part of the setHighlight function. This means that when you leave the touch, the other party will not perform.
Press on as if that solves your problem.

Highlight an item based on the validation
Hi friends,
Is it possible to highlight (or change the background color) of an element when a specific validation fails.
For example, I added a level of verification 'equipment name' validation step is unique. I have a textfield for adding equipment name
I need to display an error message "the name of the equipment is not unique" in the notification area. I need to change the color of the label of this text field name of 'red' material (not not necessary to display the error message) and highlight the text field component. Is there a way to do this. Any input on this would be appreciated.
~ Thank you
JyothiHello
You can change your label template and add some JavaScript it.

How can I change the color highlighting the e-mail messages?
Hi Hofstra64,
If you talk about the highlight appears when you select an e-mail message, this is related to the "Highlight color" parameter in your general settings of OS X. More information can be found in the following link:
Highlight color
Choose the color that you want to see when you put in highlight or select items.

How to highlight the part of the tree?
Hello everyone!
I have a question: how to highlight a part of the tree on a condition? (please see the attached vi and the pictures for a clearer explanation of the problem)
I'm using LabView 2014.
Thank you very much!
Have patience. You only aske the question about 40 minutes earlier.
You highlight the lines you want by writing the values to the control. Don't mess with the background color of cell.
You try to highlight several items? If so, then right-click on the control and let him choose 0 or more elements. As soon as you select a mode with the possibility of more than one element, the values of the tree becomes an array of strings, rather than just a string. You need build an array of strings that you will write to a local variable of the control to highlight the various elements.

To access the values from the row outside the ListView ListItem
Hello
I spent two hours browsing the forums and documentation with no chance of finding a solution on how to access the list item data from outside the listview.
Let explain me my code. It is marked with I work and what does not work and its expected behavior.
Should work behavior
Tapping & getting dataThe arrayDataModel is filled with 4 rows. Firstly the list item, second item in the list... etc.
- Tapping on the order of the day, label with the id of triggeredText displays the value of a threaded list item.
- The index of the tapped icon appears in the label with the id of triggerredIndex.
Incrementing Index using ActionItems onBar
By pressing action items 'previous' and 'next', you can increment the index value to the label with the id of triggeredIndex. The order of the index is 0-4, even as total of the items in the list.
How to extract data from the index when the value of triggeredIndex?
Buttons
The buttons at the bottom of the screen... Select 1, select the 2nd, 3rd Select should select indexes 0,1,2 of the list and display the value in triggeredText and triggeredIndex. They do not work.
How did I pull the values when you click the buttons?
import bb.cascades 1.3 TabbedPane { id: root showTabsOnActionBar: false Tab { id: mainTab title: "Test List" Page { id: mainPage titleBar: TitleBar { title: "List Traversal Test" } actions: [ ActionItem { title: "Previous" ActionBar.placement: ActionBarPlacement.OnBar onTriggered: { // get current selected index from list= var currentIndex = parseInt(triggeredIndex.text); if(currentIndex <= 0){ //do nothing already at first item }else{ // subtract 1 from index ( ci - 1) ? var newIndex = parseInt(triggeredIndex.text) - 1; // show data from new selected index // ??? // triggeredItem.text = XXX // the data // ??? // triggeredIndex.text = X // the current index triggeredIndex.text = newIndex; } } }, ActionItem { title: "Next" ActionBar.placement: ActionBarPlacement.OnBar onTriggered: { // get current selected index from list= var currentIndex = parseInt(triggeredIndex.text); if(currentIndex == 4){ //do nothing already at lastitem }else{ // add 1 to index ( ci + 1) ? var newIndex = parseInt(triggeredIndex.text) + 1 // show data from new selected index // ??? // triggeredItem.text = XXX // the data // ??? // triggeredIndex.text = X // the current index triggeredIndex.text = newIndex; } } }, ActionItem { title: "Clear" ActionBar.placement: ActionBarPlacement.OnBar onTriggered: { // set current index to 0 (top item in list) } } ] Container { preferredHeight: maxHeight layout: StackLayout { orientation: LayoutOrientation.TopToBottom } Label{ id: triggeredItem // value of listitem from current index text: "0" } Label{ id: triggeredIndex // current index text: "0" onTextChanged: { // set triggeredItem.text to contents of selected ListItem with same index // STUCK HERE cannot access ListItem.dataModel(indexPath) from here.... } } Container{ ListView { id: theList objectName: "dalist" dataModel: ArrayDataModel { id: theListModel } listItemComponents: ListItemComponent { StandardListItem { id: itemRoot title: ListItemData } } onTriggered: { var si = dataModel.data(indexPath); triggeredItem.text = "LIST ITEM CONTENT: " + si; //set content when user taps on item triggeredIndex.text = "LIST ITEM INDEX INDEX: " + indexPath; // set index when user taps } onSelectionChanged: { //console.log(selected); } onCreationCompleted: { //add some data to the listview theListModel.append("First List Item"); theListModel.append("Second List Item"); theListModel.append("Third List Item"); theListModel.append("Fourth List Item"); } } } Container{ layout: StackLayout { orientation: LayoutOrientation.LeftToRight } Button{ text: "Select 1st" onClicked: { theList.clearSelection(); theList.select(0); } } Button{ text: "Select 2nd" onClicked: { theList.clearSelection(); theList.select(1); } } Button{ text: "Select 3rd item" onClicked: { //expected behaviour is to show data from Third List Item // triggeredIndex.text = INDEX 3 // triggeredText.text = (DATA FROM THIRD LIST ITEM) // THIS IS NOT WORKING .... theList.clearSelection(); theList.select(2); console.log(theList.dataModel(3)); triggeredItem.text = theListModel.dataModel(3); } } } } } }//tab }Thank you and have a happy and healthy 2015!
Your help will be greatly appreciated.
I ran and got this:
asset:///main.qml:161: TypeError: Result of expression 'theList.dataModel' [bb::cascades::ArrayDataModel(0x1091a838)] is not a function.
But it works
theListModel.data([3])
But this isn't the solution, you have a more serious problem. You select a value, you trigger. If you add this in onTriggered you select it (and you can see that it changes color when it is selected).
theList.select(indexPath);
If you want to use option to deselect
theList.select(indexPath, !theList.isSelected(indexPath));
And if you want to have that one chose this
theList.clearSelection(); theList.select(indexPath);
Inside the button 'Select the 3rd point' allows to select programmatically
theList.select([2]);
It works but I'm not sure what you're trying to do

Pass a variable value set to the selector to the Listview
This was probably picked several times on the forum, but I'm going crazy with research and try to do things with my code.
Everything I'm doing is to expose the variable rssmobileEnabled defined in the SELECTOR, so that I can go and test it in my LISTVIEW onSelectedValueChanged IF statement, according to the code below.
I did the variable in "BOLD" below to indicate. This must be a simple solution, after all how it can be difficult to just define a global variable...
The SELECTOR code:
Picker { id: picker title: "Select Feed" dataModel: XmlDataModel { source: "models/blackberry.xml" } pickerItemComponents: [ PickerItemComponent { type: "rsslink" content: Container { layout: DockLayout { } Label { multiline: false text: pickerItemData.text textStyle { base: SystemDefaults.TextStyles.SubtitleText } } } } ] onSelectedValueChanged: { var rsslinktext = (dataModel.data([ 0, picker.selectedIndex(0) ]).text); var rsslink = (dataModel.data([ 0, picker.selectedIndex(0) ]).rssSource); var rsslinkquery = (dataModel.data([ 0, picker.selectedIndex(0) ]).rssQuery); var rssmobileEnabled = (dataModel.data([ 0, picker.selectedIndex(0)]).mobileEnabled); //Load the selected feed dataSource.load(); } } // PickerCode of the LISTVIEW:
ListView { id: myListView // Associate the list view with the data model that's defined in the // attachedObjects list dataModel: dataModellist layout: StackListLayout {} listItemComponents: [ ListItemComponent { id: header type: "header" //"item" //custom components used instead of standardlistitem Container { Label { id: emptytextheader text: "" } } }, ListItemComponent { id: item type: "item" //"description" Container { layout: DockLayout {} //custom components used instead of standardlistitem Container { id: itemdetails Label { id: title text: ListItemData.title //textStyle.fontWeight: FontWeight.Bold multiline: true textStyle.color: Color.Cyan } Label { id: pubdate text: ListItemData.pubDate textStyle.color: Color.create("#ff00c200") textStyle.fontSize: FontSize.XSmall } Label { id: description text: ListItemData.description textStyle.fontSize: FontSize.Small multiline: true textStyle.color: Color.Yellow maxHeight: 130.0 } } } } ] onTriggered: { var feedItem = dataModel.data(indexPath); var page = detailsPage.createObject(); if (rssmobileEnabled == "y") { ..... } } }Hello
"var rssMobileEnabled" declares a local variable, is not available in onTriggered.
Declare it as a property instead:
TopLevelItem { property bool rssMobileEnabled (or 'property string' if it's a character)reference it without prefix "var":
rssMobileEnabled =...
You can also declare the property on another element (not necessarily higher level) and reference it by id:
elementId.rssMobileEnabled

Highlight the last entryitem of in a query
Hello
I have the following challenge :
I would like to highlight the latest news or articles today on our intranet home page.

How to highlight the minimum value in a column?
I need to highlight the lowest value in each column in my spreadsheet. I try to use the conditional nail, but I can't find a function to work as I need.
One way would be to calculate the minutes in a cell of a footer row, select the cells in the body of the column and apply conditional highlighting like this:
You must click on the chip address first, and then select the comparison cell, A8 here, then be sure to keep the row and column.
The A8 from the example formula is = MIN (A).
The result is a bold 2 (not shown in the screenshots).
