I have a VBox inside which I have 4 HBoxes. The second level HBox is initially hidden. When I click the label, 'Show more Options', the second level HBox is displayed. Now I have the space occupied by the 'second level HBOx' empty and the 'search' button appaers below the space.
My first question is, Is there a way to position the Search Button in such a way that, the space is not there and after the 'Show more Options' label is clicked, the 'Second Level HBox' appears?
And the second question is, Can I position the Search Button at the center of the page. Is there any method to center the contents of a HBox of a VBox?
This is my code:
<mx:Form x="47" y="219" width="80%" >
<mx:VBox id="searchBox" >
<mx:HBox id="searchTitle" width="100%" height="20" backgroundColor="#2680D5">
<mx:Label text="Search Criteria" paddingRight="250" width="654.6212" height="18.030302"/>
<mx:Label text="show more options" id="moreOption" click="showOption(event)" width="127.045456" height="21.969696"/>
</mx:HBox>
<mx:HBox id="firstLevel" paddingBottom="10" paddingTop="15" >
<mx:Label text="Task Name" paddingLeft="20"/>
<mx:TextInput id="searchTaskName" paddingLeft="10" />
<mx:Label text="Item Code" paddingLeft="30"/>
<mx:TextInput id="searchItemCode" paddingLeft="10"/>
<mx:Label text="Task Type" paddingLeft="30"/>
<mx:ComboBox id="searchTaskType" paddingLeft="10"/>
</mx:HBox>
<mx:HBox id="secondLevel" visible="false" paddingTop="5">
<mx:Label text="Task ID" paddingLeft="20" />
<mx:TextInput id="searchTaskId" paddingLeft="10"/>
<mx:Label text="Project Won" paddingLeft="30"/>
<mx:ComboBox id="searchWon" paddingLeft="10"/>
</mx:HBox>
<mx:HBox>
<mx:Button label="Search" />
</mx:HBox>
</mx:VBox>
To center stuff inside a HBox, add the following attribute to the box in question,
horizontalAlign="center" width="100%"
As for the empty space created by invisible boxes (HBox or VBox), I dont know if there is any way, but I find myself adding this attribute to the invisible box,
height="{secondLevel.visible ? 200 : 0}"
Hope that helps
