#72 hwg_GetKeyboardState() and hwg_GetKeyState()

[Itamar M. Lins Jr.]

Hi!
I look into /gtk/misc.c and found the function hwg_GetKeyboardStatus()
If I'm not mistaken, it seems to me that this function doesn't work(hwg_GetKeyboardStatus)
Becouse in windows(OS) I use hwg_GetKeyState(VK_DELETE) > 0 and works
On GTK exists any similar ?

Best regards,

I wonder, who and why added the function hwg_GetKeyState() to gtk, because it's code has no any relation to a keyboard. There is no similar function in gtk.
The hwg_GetKeyboardStatus() is used to determine, if ctrl, shift and alt are pressed, and may be used in event handler only, see the hcedit.prg for example.

Hi!
I need detec the exit of a GET element.
because a user can exit get by pressing key esc.
And this way I know that he canceled the get edit.
for exemple:
A get in editing of BROWSE open another browse for search.
Function ValidMyGetOfBrowse()
if key ESC
else
oGet := value := MyFunctionBrowseElementsToChoose() //->equivalent to combobox
endif

Becouse only ON FOCUS and LOST FOCUS do not resolve this situation.

If there is a better way to solve this in Linux, I will adopt it.

You don't need this, because your bValid isn't called and a field isn't updated if ESC was pressed,
Look at hbrowse.prg, VldBrwEdit() - a function, which is used as a VALID for a GET.
