I have a couple of problems.

First, in Windows XP only when I add a new tab to a panel and then add a Editor gadget to the tab I loose the border around the Editor gadget. I did find a work around by using invalidateRect API call but I think this is a bug in the Editor or panel Gadget. (see code below for example)

Second, this is the first time I have used the panel gadget and the example below fails for calling a 'CloseGadgetList' before calling an open. It does this only after the seventh tab. I have to be missing something.

Example Code:

Code: Select all

Does anybody have any ideas on this bug? I am at a loss.

Thanks in advance

You don't need to use OpenGadgetList() for adding a panel to the panelgadget, but i think you can if you feel better about it

. But the biggest misstake you made was to to start the 'editorcount' variable at a number that is lower than the last defined gadget constant. What happened is that as this variable increases you will reach the number 7 when you will create a new EditorGadget with the same ID as the PanelGadget, the next time you try to add a panel you're actually trying to add it to the editorgadget and that's a no no...

Remember that gadget ID's should be unique unless they are static gadgets that doesn't need to be changed..

Yes, as Pupil points out you need to change
editorCount = 2
to
editorCount = #GadgetIndex

also it would work better if you changed
invalidateRect_(GadgetID(#Gadget_Form1_Panel1), 0, 1)
to
SetGadgetState(#Gadget_Form1_Panel1,panelCount-2)

Ryan, perhaps you are looking at the wrong problem. Maybe the
problem is with the EditorGadget?

I remmed out the EditorGadget create line and could then create
panels well beyond Tab 7.

I confirm that it ails here on Win98Se after 7 panels with the
EditorGadget being created.
