drag & drop

[dom3787]

Hi, I can drag & drop my gui with left click, but it won't work with right click, any idea why ?

$hGUI = GUICreate('', 800, 600, -1, -1, $WS_POPUP, BitOR($WS_EX_LAYERED, $WS_EX_TOOLWINDOW, $WS_EX_TOPMOST))

GUIRegisterMsg($WM_LBUTTONDOWN, "_WM_LBUTTONDOWN")
GUIRegisterMsg($WM_RBUTTONDOWN, "_WM_RBUTTONDOWN")

Func _WM_LBUTTONDOWN($hWnd, $iMsg, $wParam, $lParam)
    Local Const $SC_DRAGMOVE = 0xF012
    _SendMessage($hGUI, $WM_SYSCOMMAND, $SC_DRAGMOVE, 0)
EndFunc

Func _WM_RBUTTONDOWN($hWnd, $iMsg, $wParam, $lParam)
    Local Const $SC_DRAGMOVE = 0xF012
    _SendMessage($hGUI, $WM_SYSCOMMAND, $SC_DRAGMOVE, 0)
EndFunc

I tried commenting the left button part but it still won't work with right button.

Thanks for any infos.

dom3787,

If you test the code you see that the script is blocked within the "DRAGMOVE" section while the left button is pressed - while it returns instantly when called by the right button:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <SendMessage.au3>

Global Const $SC_DRAGMOVE = 0xF012

HotKeySet("{ESC}", "On_Exit")

$hGUI = GUICreate('', 800, 600, -1, -1, $WS_POPUP, BitOR($WS_EX_TOOLWINDOW, $WS_EX_TOPMOST))
GUISetBkColor(0xFF0000)

GUISetState()

GUIRegisterMsg($WM_LBUTTONDOWN, "_WM_LBUTTONDOWN")
GUIRegisterMsg($WM_RBUTTONDOWN, "_WM_RBUTTONDOWN")

While 1
    Sleep(10)

WEnd

Func _WM_LBUTTONDOWN($hWnd, $iMsg, $wParam, $lParam)
    ConsoleWrite("Left pressed at: " & @MSEC & @CRLF)
    _SendMessage($hGUI, $WM_SYSCOMMAND, $SC_DRAGMOVE, 0)
    ConsoleWrite("Left released at: " & @MSEC & @CRLF)
EndFunc

Func _WM_RBUTTONDOWN($hWnd, $iMsg, $wParam, $lParam)
    ConsoleWrite("Right pressed at: " & @MSEC & @CRLF)
    _SendMessage($hGUI, $WM_SYSCOMMAND, $SC_DRAGMOVE, 0)
    ConsoleWrite("Right released at: " & @MSEC & @CRLF)
EndFunc

Func On_Exit()
    Exit
EndFunc

Thus it appears that you cannot use the right button to drag GUIs using this method - just as you cannot use the right button to drag normal GUIs.

Now that's interesting,  but as you said "using this method". Correct me if I'm wrong but I'm pretty sure I've already came across softwares where you could actually drag & drop things using the right button, so there might be a way to do it. Apparently not this one. (I guess I'm left to use mouseevent handler and move things *while the button is pressed*)

dom3787,

Looking at the 4 methods I describe in the Moving and Resizing PopUp GUIs tutorial in the Wiki, I would be surprised if any of them worked with the right button.

Windows uses the 2 buttons to do different things (left to action, right to bring up context menus) and I feel you are asking too much to expect them to act in a similar manner just for you. Someone here might well know how to do what you want - but I do not believe it will be a simple solution and I am not holding my breath waiting for it.

Probably uneasy but doable for sure. With years I realised that speaking of computer science, about anything is possible. Only the time you want to invest in finding the answer matters. Anyway, thanks for this wiki page*, even if it's not working for the right button it definitely will improve my knowledge on the dragging topic !

 

edit :

Resizing a $WS_POPUP GUI

that script demonstrates what it has to do but fails in a way, to crash it, start the script, click with your cursor in another window or the desktop, move your cursor on your red GUI square > crash.
