Trying to focus a TextInput field in the header rendering

Hello

I have an AdvancedDatagrid and a button that, when clicked, adds a new column at the end of the datagrid.  I have a t괥 record in these new columns that contains a TextInput.  Everything works fine, except I can't get TextInput in the rendering of the header to be automatically developed after the column is added.

Right after the click on the "Add column" button, I want the user to be able to start typing in the header without having to click on it with the mouse, but it does not work.  The cursor is not in the TextInput.  However, if I start typing (you don't see anything happening), I confirmed that the value of the field actually takes the characters as I type.  Very weird.

I tried everything I can think of.  I tried setting the focus with callLater in diferent event handlers, validateNow(), etc..

A clue-

The focus won't work correctly once I added enough columns that they leave the edge of the frame and the horizontal scroll bar appears and scrolls on.

< mx:headerRenderer >

< mx:Component >

< mx:VBox horizontalScrollPolicy = "off" verticalScrollPolicy = "off" >

< mx:TextInput

Width = '100% '.

ID = "headerInput".

creationComplete = "headerInput.setFocus (); »

/ >

< / mx:VBox >

< / mx:Component >

< / mx:headerRenderer >

public void addCol (): void

    {

var col: MyCustomCol = new MyCustomCol();

var cols: Array = this.grid.columns;

    cols.push(col);

this.grid.columns = cols;

this.grid.validateNow ();

/ / Scroll the horizontal bar on the right edge to check the newly added column is visible

grid.horizontalScrollPosition = (grid.columns.length - 1);

    }              

Any ideas?

Thank you

sale tag following script in your custom header renderer and you are made, as well you can remove redundant creationcomplete setFocus.


 
override protected function updateDisplayList(unscaledWidth:Number,_unscaledHeight:Number):void {}
super.updateDisplayList (unscaledWidth, unscaledHeight);

headerInput.setFocus ();
}

  • How to manage data and create new textInput fields during the destruction/creation of new views?

    Basically, I need to know how to create another textInput field when I pass data from one view to the other, while recording the data that has been adopted in a first time.

    I want the user to be able to enter text into a textInput on the first view field and see on the next view, BUT I want the following view to record what the user has entered, return to the first view, then take another entry from the user and create another field textInput on the second point of view. It's like a memo pad app. The user enters a task on the first view, then he or she is able to see it on the second point of view. Then, the user must be able to navigate back to the first view and create another task which also goes to the second point of view, but does not replace the first task that was entered. My problem is to create new textInput fields as new data comes in for the second point of view. Any ideas? Perhaps textInput fields are not visual components I should use...

  • Setting the focus on a field without scrolling to it

    Hi all

    Basically, I implement scroll smoothly for is a VerticalFieldManager by subclassing, generating a thread and call setVerticalScroll accordingly... The result is a very nice scrolling.

    However, I also want to control the focus of the fields. However, Field.setFocus () scrolls automatically to this field... that is not what I want.

    How can I set focus to a field without the user interface infrastructure automatically scrolling to it?

    tjerkw wrote:

    I can't replace getVerticalScroll Manager: this is a final method...

    Well I've almost implemented smooth scrolling... but he jumped up and down sometimes because of the blackberry user interface infrastructure...

    Oh yes! I was wondering why I had to create a new getVerticalPosition() - that's why!

    Jumping from high to low is inevitable since these invokeLater arrive at unpredictable times.  Be sure to keep the overall pace and it will be good enough.

    Another word of warning: If you make your scroll of in a TimerTask, don't forget to cancel it when your manager scrolls smoothly becomes obscured and set one new another appointment when necessary.  If you leave it running (for example, runs at 20 Hz or so, looking for the last event not transformed), if will drain the battery like crazy...

  • How to disable the warning of validation on the calculation (read-only) field in the table

    Is it possible to add a line in a calculation script (JavaScript) that prevents a dialog box of a calculation field validation?

    Scenario:

    • Working with fields in a table inserted.
    • In each line, I have a couple of fields that the user has entered. These fields have a Validation model has allowed that the user must enter the data correctly.
    • There is a calculated field based on the data entered by the users. It is this field that throws a warning dialog box "the value entered for Total_Row1 is not valid. "To ignore the validations for Total_Row1, click on ignore.

    Even if I turn off the Model Validation on fields used for the calculation of the warning dialog box always appears. So, it seems to be isolated in the field of computing.

    The calculation area displays the time and I got it originally set as a Date/time field, but also tried to use a text field (as the calculation should appear as 0:45 for 45 minutes in this area).

    I have a suspicion that the warning appears only because I used an array for formatting fields, as I used similar validation profiles and other calculation fields and see not the message when the fields do not appear inside the table.

    I think of easier workaround would be to disable validation for this particular calculation field, but I have no idea how the script that. Any help appreciated lot.

    CARI

    I discovered the problem.  In a word: it was a mistake by naming the fields.

    • I have fields named with line numbers in the field name (for example FieldName_Row1).
    • and fields calls with FieldName_Row1.formattedVallue must have triggered some confusion.

    As soon as I removed the word 'Row' of file names, the question of the warning dialog validation mystery Adobe Acrobat for the calculation field have disappeared.

    Ago about 3-4 hours of my life that I won't be back... ha - ha but if someone else has the problem, I thought I better share my discoveries

  • To display the header field on each page

    Hi all

  • Repeat the field values by repeating the header (flowed subform)

    I have a request form which consists of three main sections - a header, a table of details, and a footer.

    The Details table must be able to expand to fit, which means that the form should be able to escape on a second page. All the fields in the header must repeat on the second page. The footer should only appear once, at the bottom of the table of details, not repeated on each page.

    After much tinkering with flowed and positioned subforms, I've got this work with the Details table inside a subform sank, with a subform positioned in the lines of header and footer in the table. I suspect that this is not the 'proper' way, but it's the only way I could make it work.

    So my head joyfully repeats on the second page, but the values typed in the first page header fields do not appear on the second page. The user must be able to change the header on any page and all pages update headers.

    Can someone please point me to a tutorial or give me an idea of what code would accomplish this? I don't know how to reference the field repeated to set its value.

    If I do it is crazy, and there is a better way, it would be good to know too. I use es2

  • Is there a way to remove the header (office) completely?

    Hello

    The layout Azure_Blue Robohelp 2015 provides works perfectly in my case, except the header. The generated content will be incorporated into a web portal that already has a heading of its own. I can do the background, the police and white logo - making the header 'invisible '. But the empty space still seems too clumsy. In addition, the sidebar already has a search function, then the search field in the header is not necessary. Any help would be appreciated! Thank you.

    The CSS uses positioning to set the header and content. So when removing the header, you will also need to correct the positioning.

    1. Download the source SCSS files: layouts and RoboHelp screen profiles
    2. Open the Azure_Blue\Layout.scss file in Notepad ++ or any editor of your choice
    3. On line 1371, set the variable $heading - height - Office to 0em. This will fix all the calculations of the height in the SCSS to ensure everything is well positioned now.
    4. Online 1427, add display: none! important;
    5. Online 1628, add display: none! important;

    Save the file and generate the CSS file with a compiler SCSS like Koala. Add the CSS to your provision of the screen and you should be good to go.
