How to disable TabStop for a Radio Button

Recommended Posts

AlainB

Is there a way to disable the TabStop for the Radio button on this script?

With the "_Winapi....." line it is working but only partially. If I click on one of the radio button, the tabstop start to work again.

I cannot use Hotkeyset because I will run multiple instance of the script.

Thanks!

Alain

#include <Constants.au3>

#include <WinAPI.au3>

#include <GUIConstantsEx.au3>

#include <WindowsConstants.au3>

$Form1 = GUICreate("Test", 288, 284,-1,-1)

$Input1 = GUICtrlCreateInput("", 12, 8, 57, 21)

_WinAPI_SetWindowLong(GUICtrlGetHandle(-1), $GWL_STYLE, BitAND(_WinAPI_GetWindowLong(GUICtrlGetHandle(-1), $GWL_STYLE), BitNOT($WS_TABSTOP)))

$radio1 = GUICtrlCreateRadio("Radio1", 150, 8, 55, 21)

GUICtrlSetState($radio1, $GUI_CHECKED)

_WinAPI_SetWindowLong(GUICtrlGetHandle(-1), $GWL_STYLE, BitAND(_WinAPI_GetWindowLong(GUICtrlGetHandle(-1), $GWL_STYLE), BitNOT($WS_TABSTOP)))

$radio2 = GUICtrlCreateRadio("Radio2", 210, 8, 55, 21)

_WinAPI_SetWindowLong(GUICtrlGetHandle(-1), $GWL_STYLE, BitAND(_WinAPI_GetWindowLong(GUICtrlGetHandle(-1), $GWL_STYLE), BitNOT($WS_TABSTOP)))

GUISetState(@SW_SHOW)

While 1

$nMsg = GUIGetMsg()

Switch $nMsg

Case $GUI_EVENT_CLOSE

Exit

EndSwitch

WEnd

Just bumping up my post.

The "winAPI...." lines in the script are lines that I took from another thread and they are working fine for inputs. They are not working well for Radio button.

Would there be another way to do what I want to do?

Many thanks!

AlainB,

Interesting behaviour! :graduated:

It seems it is actually Windows doing it each time the Radio control is actioned via the BM_SETCHECK message:

"BM_SETCHECK - Sets the check state for all styles of radio buttons and check boxes. If the wParam parameter is greater than zero for radio buttons, the button is given the WS_TABSTOP style."

It seems the only solution is to reclear the TABSTOP style each time a Radio is actioned:

#include <Constants.au3>
#include <WinAPI.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
 
$Form1 = GUICreate("Test", 288, 284, -1, -1)
 
$Input1 = GUICtrlCreateInput("", 12, 8, 57, 21)
_No_TABSTOP($Input1)
$radio1 = GUICtrlCreateRadio("Radio1", 150, 8, 55, 21)
GUICtrlSetState($radio1, $GUI_CHECKED)
_No_TABSTOP($radio1)
$radio2 = GUICtrlCreateRadio("Radio2", 210, 8, 55, 21)
_No_TABSTOP($radio2)
GUISetState(@SW_SHOW)
 
While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $radio1, $radio2
            _No_TABSTOP($nMsg)
    EndSwitch
WEnd
 
Func _No_TABSTOP($iCID)
 
    _WinAPI_SetWindowLong(GUICtrlGetHandle($iCID), $GWL_STYLE, BitAND(_WinAPI_GetWindowLong(GUICtrlGetHandle($iCID), $GWL_STYLE), BitNOT($WS_TABSTOP)))
 
EndFunc

Or you are into subclassing the Radio controls to change the WndProc - that I will leave to someone else! :)

Edit: A bit more reading and I can see this behaviour is actually logical. Normally you have only the one Radio checked at any one time and that is the one to which you would want Windows to move the focus when you press the TAB key. So when setting a Radio to checked Windows will automatically reset the TABSTOP property for that control. At least you only need to clear the property for the checked control (as shown in the code above) and not all of them every time. ;)
