The commands WindowEvent() and WaitWindowEvent() seem to intervene the TAB keyboard key.
I work with a edit custom control and all seems to work fine except that the TAB key doesn't work (doesn't pass through the custom control).

If I use Windows API like:
(example) instead of WindowEvent() or WaitWindowEvent() all works fine.

A possible answer from the PB manual:

Add or replace a keyboard shortcut to the specified #Window. A shortcut generates a menu event (like a menu item) as most of them are used in conjonction with menus. The EventID is the number which will be returned by the EventMenuID() command. By default, a window already has the #PB_Shorcut_Tab and #PB_Shortcut_Tab|#PB_Shortcut_Shift shortcuts to handle tab and shift-tab correctly trough the gadgets. A shortcut can be removed with RemoveKeyboardShortcut().

Try PolyVector's TabStop tip, and apply it to the custom control:

Should fix the problem. (BTW, this isn't a bug, since you're using a custom
control that PureBasic doesn't natively support).

The tab key is automatically added to each window as a shortcut to jump
between the gadgets. Shortcuts are processed before passing on the
Message to the WindorProc it belongs to, that's why you get nothing.

With RemoveKeyboardShortcut() you can remove this easily.

The reason why your api code works is that it doesn't call TranslateAccelerator_(), which handles the shortcuts.

Kale,
I don't won't to ADD the TAB key.
It's already there.... but not working because of PB.

EDIT: you are right, there it says:

• By default, a window already has the #PB_Shorcut_Tab and #PB_Shortcut_Tab|#PB_Shortcut_Shift shortcuts to handle tab and shift-tab correctly trough the gadgets.

I missed that.
Now I stand corrected too...
Thanks

PB,
no offence, but you are wrong.
This has nothing to do with a specific custom control, it's just an example.
It's PB that is cutting off the messages from the os...

Thanks

Timo,
just looked at the manual and you are right:

• By default, a window already has the #PB_Shorcut_Tab and #PB_Shortcut_Tab|#PB_Shortcut_Shift shortcuts to handle tab and shift-tab correctly trough the gadgets. A shortcut can be removed with RemoveKeyboardShortcut().

But nevertheless, IMO the way it is now, is not OK.
Normally if the user wants special functionality like: shortcuts to handle tab and shift-tab correctly trough the gadgets, this should be added through a command or through a parameter for WaitWindowEvent() and WindowEvent(), and not automatically added.

Like: WaitWindowEvent(#PB_ADD_GADGETS_TAB)


Maybe I should add this to the PB_Wishlist.

Thanks

EDIT: maybe WaitWindowEvent(#PB_USE_DIALOGSTYLE_TABS) is better, but it's up to the PureBasic Coding Team

BTW:
@FREAK,
If you are a admin you could move this topic to the WISHLIST section.

Thanks

Jumping between Gadgets with the Tab key is basic functionality, why should
everybody be required to add that on his own?

No it's not.
At least not for normal Windows.
It's a special functionality from a Dialog Window.

PureBasic doesn't have DialogWindow(...)
But that is another story...

EDIT: @Freak: Thanks for moving...

No offence taken at all.

Well you did say that Tab didn't pass through a custom control, so that's why
I thought it wasn't working, because PureBasic didn't recognize the control.

> It's PB that is cutting off the messages from the os...

Yep, I've read Freak's explanation, and I stand corrected.

Hope this wish makes it in v4...
