Question

How do I remove the space between tab button and border container.

The code is

<s:TabBar dataProvider="{vsApplication}" >

 <s:layout>
  <!--<s:ButtonBarHorizontalLayout gap="7" />-->
  <s:HorizontalLayout gap="7" paddingBottom="0"/>
 </s:layout>

 </s:TabBar>

 <mx:ViewStack id="vsApplication" width="100%">

  <s:NavigatorContent id="ncConfiguration" label="Configuration" width="100%">
   <s:BorderContainer width="100%">

   </s:BorderContainer>
  </s:NavigatorContent>

  <s:NavigatorContent id="ncProject" label="Project" width="100%">
   <s:BorderContainer width="100%">
   <mx:DataGrid id="dgProject" dataProvider="{projectData}" doubleClickEnabled="true" itemDoubleClick="dgProject_itemDoubleClickHandler(event)">
    <mx:columns>
     <mx:DataGridColumn headerText="Project ID" dataField="ProjectID"/>
     <mx:DataGridColumn headerText="Project Name" dataField="ProjectName"/>
     <mx:DataGridColumn headerText="Planned Start Date" dataField="PlannedStartDate"/>
     <mx:DataGridColumn headerText="Planned End Date" dataField="PlannedEndDate"/>
     <mx:DataGridColumn headerText="Actual Start Date" dataField="ActualStartDate"/>
     <mx:DataGridColumn headerText="Actual End Date" dataField="ActualEndDate"/>
    </mx:columns>
   </mx:DataGrid>
   </s:BorderContainer>
  </s:NavigatorContent>

  <s:NavigatorContent id="ncTimesheet" label="Timesheet" width="100%">
   <s:BorderContainer width="100%">

   </s:BorderContainer>
  </s:NavigatorContent >

  <s:NavigatorContent id="ncDashboard" label="Dashboard" width="100%">
   <s:BorderContainer width="100%">

   </s:BorderContainer>
  </s:NavigatorContent>

 </mx:ViewStack>

Answer 1

I had a similar problem – no padding or gap specified anywhere, but there was a space between the TabBar and the ViewStack.

The fix was to set gap="0" in the layout of the parent component (in my case a Panel with VerticalLayout).
