I've been able to successfully insert a horizontal panel that also
contains a vertical panel as a tab. I used composition to create my
split panel and added that to the tab panel.
For example:
DecoratedTabPanel tabPanel = new DecoratedTabPanel();
...
class MyTab extends Composite {
private final HorizontalSplitPanel container;
private final VerticalSplitPanel tabPanel;
public MyTab(){
container = new HorizontalSplitPanel();
initWidget(container);
tabPanel = new VerticalSplitPanel();
container.setLeftWidget(tabPanel);
...
// set size to 100%, set split position, etc...
...
}
...
public DecoratedTabPanel getTabPanel(){
return container;
}
...
}
....
tabPanel.getTabPanel().insert(myTab, "My Tab", 0);
I've also noticed that whatever tab is selected upon loading looks
fine, but any other tab's content doesn't seem to show up properly.
I'm not sure why this is, I've never really researched it, but I've
found the following method helpful to ensure proper layout when called
in onModuleLoad().
public static void cycleTabs(TabPanel tabPanel){
if(tabPanel == null) { return; }
int tabCount = tabPanel.getTabBar().getTabCount();
for(int i=tabCount; i>0; i--){
tabPanel.selectTab(i-1);
}
}
Let me know if this helped.
