add a size grip with DrawFrameControl

[jennico]

hi there

i wonder why this has not been asked before:

i want to add a size grip to a sizable GUI ($WS_SIZEBOX) without statusbar. can anyone give me an example ? all i can do is just guess: i need a WM_PAINT event or is it WM_NCHITTEST ? the function should be:

Func DrawFrameControl($hDC, $nLeft, $nTop, $nRight, $nBottom, $nType, $nState)
    Local Const $DFC_SCROLL = 3,$DFCS_SCROLLSIZEGRIP = 8    
    Local $stRect = DllStructCreate("int;int;int;int")

    DllStructSetData($stRect, 1, $nLeft)
    DllStructSetData($stRect, 2, $nTop)
    DllStructSetData($stRect, 3, $nRight)
    DllStructSetData($stRect, 4, $nBottom)

    DllCall("user32.dll", "int", "DrawFrameControl", "hwnd", $hDC, "ptr", DllStructGetPtr($stRect), "int", $DFC_SCROLL, "int", $DFCS_SCROLLSIZEGRIP)

    $stRect = 0
EndFunc  ;==>DrawFrameControl

so the size grip is originally a scrollbar element. but what would be the device context (the window ?), and what is the rectangle (client size bottom right 16 x 16 ?)in this case ?

(btw: on the other hand, one could simply place an icon, but where to find it ?)

can anyone provide a working example using DrawFrameControl ?

thx j.

#include <WindowsConstants.au3>
#Include <WinAPI.au3>
Opt("TrayIconDebug", 1)
$Gui = GUICreate("", default, default, default, default, $WS_SIZEBOX)
$DC = _WinAPI_GetDC($Gui)
GUISetState()

DrawFrameControl($DC, 10,10,100,100)

while 1 
WEnd


Func DrawFrameControl($hDC, $nLeft, $nTop, $nRight, $nBottom)
    Local Const $DFC_SCROLL = 3,$DFCS_SCROLLSIZEGRIP = 8    
    Local $stRect = DllStructCreate("int;int;int;int")

    DllStructSetData($stRect, 1, $nLeft)
    DllStructSetData($stRect, 2, $nTop)
    DllStructSetData($stRect, 3, $nRight)
    DllStructSetData($stRect, 4, $nBottom)

    DllCall("user32.dll", "int", "DrawFrameControl", "hwnd", $hDC, "ptr", DllStructGetPtr($stRect), "int", $DFC_SCROLL, "int", $DFCS_SCROLLSIZEGRIP)
MsgBox(0, "", @error)
    $stRect = 0
EndFunc  ;==>DrawFrameControl

I leave the rest to you...

PS ALOT of icons can be found within various dll's...

Also you can make your own.

$DC = _WinAPI_GetDC($Gui)

....so easy, can't believe it, thanx

You really should put the drawing in WM_PAINT. Then it won't disappear

expandcollapse popup

#include<WindowsConstants.au3>
#include<GUIConstantsEx.au3>
Global $hGUI = GUICreate("Sizetest", default, default, default, default, $WS_SIZEBOX)
GUIRegisterMsg($WM_PAINT, "_MY_WM_PAINT")
GUISetState()
While GUIGetMsg()<>-3
WEnd

Func _MY_WM_PAINT($hWnd, $uMsg, $wParam, $lParam)
    ; Init paint
    Local $tPS = DllStructCreate("ptr hdc; BOOL fErase;long rcPaint[4]; BOOL fRestore; BOOL fIncUpdate; BYTE rgbReserved[32];")
    Local $aPaint = DllCall("user32.dll", "handle", "BeginPaint", "hwnd", $hWnd, "ptr", DllStructGetPtr($tPS))
    If @error Then Return $GUI_RUNDEFMSG
    Local $hDC = $aPaint[0]

    ; Draw
    Local $pos = WinGetClientSize($hWnd)
    DrawFrameControl($hDC, $pos[0]-10, $pos[1]-10, $pos[0], $pos[1])

    ; Finish Paint
    DllCall("user32.dll", "bool", "EndPaint", "hwnd", $hWnd, "ptr", $aPaint[2])

    Return $GUI_RUNDEFMSG
EndFunc
Func DrawFrameControl($hDC, $nLeft, $nTop, $nRight, $nBottom)
    Local Const $DFC_SCROLL = 3,$DFCS_SCROLLSIZEGRIP = 8
    Local $stRect = DllStructCreate("int;int;int;int")

    DllStructSetData($stRect, 1, $nLeft)
    DllStructSetData($stRect, 2, $nTop)
    DllStructSetData($stRect, 3, $nRight)
    DllStructSetData($stRect, 4, $nBottom)

    DllCall("user32.dll", "int", "DrawFrameControl", "hwnd", $hDC, "ptr", DllStructGetPtr($stRect), "int", $DFC_SCROLL, "int", $DFCS_SCROLLSIZEGRIP)

    $stRect = 0
EndFunc  ;==>DrawFrameControl

hmm i made it with WM_NCHITTEST .

#include <WindowsConstants.au3>
;#Include <WinAPI.au3>

Global Const $DFC_SCROLL = 3,$DFCS_SCROLLSIZEGRIP = 8    
$Gui = GUICreate(" Size Grip Window", 400, 300, default, default, $WS_SIZEBOX)

GUIRegisterMsg($WM_NCHITTEST , "DrawFrameControl")

GUISetState()

Do
    Sleep(20)
Until GUIGetMsg() = -3



Func DrawFrameControl($hWndGUI, $MsgID, $WParam, $LParam)
    Local $stRect = DllStructCreate("int;int;int;int")
    Local $stSize = WinGetClientSize($hWndGUI)
    Local $hDC = DllCall("User32.dll", "hwnd", "GetDC", "hwnd", $hWndGUI)   
    
    DllStructSetData($stRect, 1, $stSize[0] - 16)
    DllStructSetData($stRect, 2, $stSize[1] - 16)
    DllStructSetData($stRect, 3, $stSize[0])
    DllStructSetData($stRect, 4, $stSize[1])

    DllCall("user32.dll", "int", "DrawFrameControl", "hwnd", $hDC[0], "ptr", DllStructGetPtr($stRect), "int", $DFC_SCROLL, "int", $DFCS_SCROLLSIZEGRIP)
    
    DllCall("User32.dll", "int", "ReleaseDC", "hwnd", $hWndGUI, "hwnd", $hDC[0])
    $stRect = 0
EndFunc  ;==>DrawFrameControl

seems the same.

edit: @progandy: _MY_WM_PAINT does not work for me (xpsp3)

You need the current version of AutoIt. Do you have it?

[jennico]

i admit, no.

does this matter ? wm_paint was working before, didn't it ?

DLLCall and DLLStructCreate have got new types wich I'm using. You have to change them to the old ones (bool -> int, handle -> ptr, ...)

[jennico]

ok, this is a sizing window with custom status bar (much easier than the system statusbar) and custom size grip.

expandcollapse popup

#include <WindowsConstants.au3>
;#Include <WinAPI.au3>

Global Const $DFC_SCROLL = 3,$DFCS_SCROLLSIZEGRIP = 8    
$Gui = GUICreate(" Size Grip Window", 400, 300, default, default, $WS_SIZEBOX)

$size=WinGetClientSize($Gui)
GUICtrlCreateLabel("", 0, $size[1] - 18, $size[0], 18, -1, $WS_EX_STATICEDGE)
GUICtrlSetResizing(-1, 582)

GUIRegisterMsg($WM_NCHITTEST , "DrawFrameControl")

GUISetState()

DrawFrameControl($Gui, 0, 0, 0)

Do
    Sleep(20)
Until GUIGetMsg() = -3



Func DrawFrameControl($hWndGUI, $MsgID, $WParam, $LParam)
    Local $stRect = DllStructCreate("int;int;int;int")
    Local $stSize = WinGetClientSize($hWndGUI)
    Local $hDC = DllCall("User32.dll", "hwnd", "GetDC", "hwnd", $hWndGUI)   
    
    DllStructSetData($stRect, 1, $stSize[0] - 17)
    DllStructSetData($stRect, 2, $stSize[1] - 17)
    DllStructSetData($stRect, 3, $stSize[0] - 1)
    DllStructSetData($stRect, 4, $stSize[1] - 1)

    DllCall("user32.dll", "int", "DrawFrameControl", "hwnd", $hDC[0], "ptr", DllStructGetPtr($stRect), "int", $DFC_SCROLL, "int", $DFCS_SCROLLSIZEGRIP)
    
    DllCall("User32.dll", "int", "ReleaseDC", "hwnd", $hWndGUI, "hwnd", $hDC[0])
    $stRect = 0
EndFunc  ;==>DrawFrameControl

very nice, looks just like explorer.

now this has been done with AutoIt

thx again, j.

edit: $WM_EXITSIZEMOVE = 0x0232 would probably be the most correct event.
