Flex :: Set Text Property On KeyDownHandler On TextInput?
Oct 11, 2011
I extended a mx.controls.TextInput to create a custom component with a different behavior.I'm trying to set the text property on the keyDownHandler(), and for some reason it doesn't work as I expected. The text on the component just kinda ignore the change.I'm using Flex 3.6.Down here is a simple example code that explains what's going on:
I'm trying to convert an MXML component to an ActionScript Class. The component consists of a Form with a TextInput, TextArea, and two buttons - Save and Cancel, and a Validator for the TextInput, and other logic to handle events that occur. This component is currently extended by several other components. Now, in the MXML component binding the TextInput text property to a property in an Object was very easy: <mx:TextInput text="{_itemToEdit.name}" />
But in ActionScript, I'm creating the TextInput and setting the text property before the Object is set, and the TextInput is not being updated: public var itemToEdit:Object = {}; private var nameInput:TextInput = new TextInput(); public function MyClass() { nameInput.text = itemToEdit.name; }
How can I make sure that the TextInput text property is bound to the specified property in the Object?
So the real problem is the lack of an onReleaseOutside function. I found some examples of how to bypass this during a drag function but it was not applicable for a text input.The problem is that when a user selects some text in textinput and mouses off the application area and then mouses up, I'm getting a problem that the textinput keeps thinking that the mouse down is actively selecting text in the textinput and continually overwrites the characters being entered in the textinput. in the search bar of the live store on the page, type some text, then highlight it all and don't let up on the mouse until you are outside the store.I finally hacked some junk together so I can tell if the mouse goes off the stage using some code like.
var x = stage.mouseX;var y = stage.mouseY;if(x < 0 || y <0 || x >stage.stageWidth || y > stage.stageHeight)I'd like to just make the textinput stop thinking it should be highlighting text so that even if the user scrolls out of the applet and mouses up that the text input still overwrites what is in the search bar and functions as normal.
Setting the text property of a flex DateField makes the selectedDate property of that DateField go to null.I need to set the text property so that I can use a particular format (DD-MMM-YYYY).
I'm using Flashbuilder 4. I have a Spark TextInput control, and I'm implementing a "Copy" button that will copy the selected text only from within this control to the clipboard (pretty much like the RMB Copy does).
I want to have the mouse cursor to be changed to hand when used for entering the<mx:textInput>. When the field is already on focus, text selection should be available.I tried any combination of useHandCursor="true", buttonMode="true" and mouseChildren="false",and the closest result is when using all three of them. Then the hand cursor does appear, but the text field loses its selection 'abilities' (text cannot beselected using the mouse). This is logical, since mouseChildren="false" disables this. But how do I acheive the desired result?
I have a Flex3 TextInput control, with white text on a black background. I would like to change the style of highlighted text within the control to use black text on a white background (or something similar). I would love to do this using Flex styles, however I'm comming up empty handed
I have an application which displays employee information. If the user opening the detailed employee information page is not authorized to make changes I set the TextInput to disabled. Some users are reporting rendering issues with this. The TextInput's text value does not appear inside the box but is misaligned and is outside of the component. You can see the screenshow below of the disabled ID column where the numbers which are supposed to be in the TextInput box are far off to the right.
Because the color of the background image in my application is very dark, and the Alpha is very low, when I hover my mouse over a checkbox, the text is scarcely visible. I've scoured the interwebz in vain for what property to set, either at design-time or in the MouseOver event for the checkbox and just can't figure out what property or setStyle property to alter to be able to control the color of the checkbox text when the mouse pointer is hovering over it.
I'm looping through a recordset, and for each item I create at runtime a spark Label and set the text property from a field of the recordset. The labels must have a fixed width and some text goes multiline. I want to arrange the label vertically so I need to know the height of the label so I can place the next label properly, but when I try to read this property, after the labels is added through the addElement mehtod, it returns 0.
I am using a custom itemEditor for my DataGrid.The itemEditor has a simple TextField as a component.But when ever i am clicking the cell i am getting an error as [code]My Opinion is that the error is coming for the "text" field. But i havn't accessed "text" field or used it anywhere in my code.
I am using the combocheck example from the following site: [URL]
It's a very useful component and works very well.
Now, I need to set the text property of this combo box upon application startup with certain values (which are defined dynamically according to some criteria). The problem is that although I have no problem setting the text property of the combo box at other times of the application run, setting the property at startup seems to have no effect unfortunately.
For example, I want to set the text property of the combobox to "Bob" (which is one of the items in the dataprovider for the combobox) and the "set text" method is called on the combo box. Performing a step-through shows that the "set text" method is receiving the correct value item but not setting the _text property.
I have tried not doing anything until "ApplicationComplete" but no joy there either.
Here is the code (a combination of the code from the URL above and some other changes to it). However, as I've stated above, the codes does work. The problem is that it doesn't work at the application startup. Whenever an event is fired and setComboText is called as a result, the text of the combo box is set correctly.
private function onComboChecked(event:ComboCheckEvent):void { var obj:Object=event.obj; var index:int=selectedItems.getItemIndex(obj);
I have a textArea in my main application as[code]...
I have another mxml file in which I access that textArea as[code]...
I am able to append text via following command which does not seem a good option or is it? Won't following line of code by inefficient if size of text in the Text Area increases considerably?

I have a textInput component on stage. There is also push button component. the user types his name in the textInput box, and when he presse the button it goes to the next frame, transferring the value of the textInput box to a dynamic text box on frame 2.
