Re: [flexcoders] List / DataGrid height problem

Hi Matt,

i tried a real value and undefined instead of 100%, didn't help. Perhaps you have another idea, otherwise I have to change my layout. I prefer the first option ;-)

Good night
Christoph

I’m not sure that the percentages are really going to work within a cell renderer. Basically if you have a preferred height the row will size to that row. But if you give it a percentage the row doesn’t know how tall you really are meant to be. So maybe try using a real value instead of 100%? Even undefined might actually be the right value so that it tries to size to the preferred size of the children.

Hi Matt,

you are right. I give you some snippets of my code.

List / DataGrid

<mx:List id="Aufgabenliste" width="100%" height="100%"
variableRowHeight="true" dataProvider="{aufgabenData}"
cellRenderer="aufgaben.AufgabenCellRenderer"></mx:List>
<!-- <mx:DataGrid id="Aufgabenliste" width="100%" height="100%"
variableRowHeight="true">
<mx:dataProvider>
{aufgabenData}
</mx:dataProvider>
<mx:columns>
<mx:Array>
<mx:DataGridColumn headerText="{gridTitle}"
cellRenderer="aufgaben.AufgabenCellRenderer" />
</mx:Array>
</mx:columns>
</mx:DataGrid>

Part of my CellRenderer (AufgabenCellRenderer)

function doResize(){
var aufgViewHelper =
ViewLocator.getInstance().getViewHelper( "aufgabenView" );
if(close){
aufgabePanel.height="100%";
close = false;
state = "schließen";
}
else{
aufgabePanel.height=28;
close = true;
state = "öffnen";
}
aufgViewHelper.refreshList(this);
}

]]>
</mx:Script>

<mx:Panel id="aufgabePanel" title="{name}" status="{state}"
height="28" width="100%" mouseDown="doResize()">
<mx:Form>
<mx:FormItem label="Anfang">
<mx:Label text="{startDate}" />
</mx:FormItem>
<mx:FormItem label="fertig bis">
<mx:Label text="{endDate}"></mx:Label>
</mx:FormItem>
<mx:FormItem label="Priorität">
<mx:Label text="{priority}" />
</mx:FormItem>
<mx:FormItem label="Status" >
<mx:Label text="{status}" />
</mx:FormItem>
</mx:Form>
</mx:Panel>

I should mention, that the List / DataGrid is in a HBox beside another
List. If I change the size of one of the lists the row with the
CellRenderer is shown correctly once, then the height of the row is
static again.
Can I broadcast the HBox change event manually?

I assume you have variableRowHeight set to true?

Hi List,

I have some trouble with my custom CellRenderer. It is Panel wich
expands when you click on it. The initial height is 28pt and when it
expands, it has the height it needs.
The Problem is, that when you click on it, the Panel expands as
expected, but the row height doesn't change. I only get a scrollbar on
the right side of the row. I tried several things, like draw() the list,
but nothing helped.

Any ideas?

Thanks a lot
Christoph
