Hi together,

when I create a lot of tabpages on a TabControl programmatically with OpenTab, the left/right arrow buttons to scroll through all the tabpages are not displayed.

Trying with Multiline TRUE/FALSE didn't work.

 

Anybody an idea how can I display the arrow buttons?

 

Thanks in advance,

Bernhard

Hi Bernhard;

  Thought ... try resizing the TC a bit. For example, after the OpenTab command: 

  • TC.Width ++
  • Yield()
  • TC.Width --

See if that forces the arrows on.

Regards ... Chris

Yup, resizing an object forces a redraw of every item on that base object.

Hi Chris,

thank you very much for your suggestion, this works for me, because it showed me a mistake in calculating the tab width while resizing.

The resized tab was to wide so the arrows were hidden behind the parent window. After adjusting now it works fine!

Regards,

Bernhard
