TabStrip does not work

Hello community and Manuel,

I think there is something wrong with the TabStrip control. I do the following:
1. Open a TabStrip on Form1.
2. Add two UserControls.
3. Add the TabStrip1.Tabs.Add command to main module.
4. Start the project.
5. Now I see the attaching screen (Form1) and
6. and get this exception twice:

Source code

Exception in thread "AWT-EventQueue-1" java.lang.ArrayIndexOutOfBoundsException: 0
 at javax.swing.plaf.basic.BasicTabbedPaneUI.paintTabArea(BasicTabbedPaneUI.java:825)
 at javax.swing.plaf.basic.BasicTabbedPaneUI.paint(BasicTabbedPaneUI.java:780)
 at javax.swing.plaf.ComponentUI.update(ComponentUI.java:143)

Perhaps it is my mistake, but I do not know.
Thanks for tips.

Cheers
Stefan

Hi Stefan,

in Jabaco Version 1.5.0 unfortunately there is in fact a problem with Tabstrips, the problem is even bigger:
already instantiated usercontrol-objects get deleted if you open your project again later.
But you can see TabStrips working, because you also made a mistake:
between point 2 and point 3 you must place the usercontrol from the Tools-bar to your Form.

go this way:
1. in Formdesigner dragdrop a TabStrip on Form1.
2. in projectexplorer, for every tab Add one UserControl to your project
2.a in every Formdesigner of your usercontrols, design your tabs
2.b back agin to Formdesigner of your Form, dragdrop 1 usercontrol-object per tab from the tools-bar to your form.
3. Add the TabStrip1.Tabs.Add command to (not main module but) Form_Load
4. Start the project

	Jabaco Source
1 2 3 4	Public Sub Form_Load() TabStrip1.Tabs.Add(TabOptionPath1, "Path") TabStrip1.Tabs.Add(TabOptionEdit1, "Edit") End Sub

Now you should see your tabstrip working
