Have you been able to move a Datagrid’s vertical scrollbar to the left side without issue? When using the method you listed above it moves the scrollbar but not the header for the scrollbar, nor does it move the other columns over. The scrollbar basically sits on top of the first rows data in a Datagrid. Any help would be great. Thank you.

First – sorry of my English, I don’t use this language.

My question :

Hou use this example?

my class like this :

package {

import mx.controls.TextArea;

public class MyClass extends TextArea {

protected override function updateDisplayList (unscaledWidth:Number, unscaledHeight:Number):void {
super.updateDisplayList (unscaledWidth, unscaledHeight);
if( verticalScrollBar && verticalScrollBar.visible ) {
verticalScrollBar.x = -verticalScrollBar.width;
}
}

}
}

n Flex :

Jacob, I just wrote this simple program that uses the last version. It creates two text areas, on with scrollbar on right (default) and one on the left (as above).

Created a Flex Project called TextAreaControl.mxml

Then created an actionscrip file to hold my custom component.

package myComponents
{
import mx.controls.TextArea;

public class MyCustomComponentTextArea extends TextArea
{
public function MyCustomComponentTextArea()
{
super();
}

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

if( verticalScrollBar && verticalScrollBar.visible )
{
//verticalScrollBar.x = -verticalScrollBar.width;
verticalScrollBar.x = 0;
textField.x=verticalScrollBar.width;
}
}
}
}

Hi there,
Perhaps a stupid question, but i am wondering; Do you need to call that new class in your project?
Can you give a working example please?

Greets, Jacob

nice one – was just thinking maybe to prevent it messing up the size calculations of the component you could do the following:

protected override function updateDisplayList( unscaledWidth:Number, unscaledHeight:Number ):void
{
super.updateDisplayList( unscaledWidth, unscaledHeight );
if( verticalScrollBar && verticalScrollBar.visible )
{
//verticalScrollBar.x = -verticalScrollBar.width;
verticalScrollBar.x = 0;
textField.x=verticalScrollBar.width;
}
}
