Replace Edit control context menu with your own

maillady · August 28, 2012

Hi,

This example demonstrates how to replace the default context menu in an edit control with your own

Uses _WinAPI_CallWindowProc, a good function that requires more examples :ILA:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <Constants.au3>
#include <GuiMenu.au3>
#include <WinAPI.au3>
#include <GUIEdit.au3>

; modified from help example: _WinAPI_CallWindowProc

$hGui = GUICreate("Custom context menu for Edit Control example", 489, 354, -1, -1)
$editBox = GUICtrlCreateEdit("", 8, 40, 473, 305)
GUICtrlSetData(-1, "New text")
$checkBox = GUICtrlCreateCheckbox("Use our own context menu", 8, 8, 241, 17)
GUICtrlSetState($checkBox, $GUI_CHECKED)

;!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
;!! subclass for $editBox
$w_editBoxProcNew = DllCallbackRegister("_MyWindowProc", "ptr", "hwnd;uint;long;ptr")
$w_editBoxProcOld = _WinAPI_SetWindowLong(GUICtrlGetHandle($editBox), $GWL_WNDPROC, DllCallbackGetPtr($w_editBoxProcNew))
_WinAPI_SetWindowLong(GUICtrlGetHandle($editBox), $GWL_WNDPROC, DllCallbackGetPtr($w_editBoxProcNew))

;!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
;!! our context menu for $editBox
$DummyMenu = GUICtrlCreateDummy()
$ContextMenu = GUICtrlCreateContextMenu($DummyMenu)
$TestMenuItem = GUICtrlCreateMenuItem("Our Custom Context Menu", $ContextMenu)
GUICtrlSetState($TestMenuItem, $GUI_DEFBUTTON)
GUICtrlCreateMenuItem("", $ContextMenu)
$UndoMenuItem = GUICtrlCreateMenuItem("&Undo", $ContextMenu)
GUICtrlCreateMenuItem("", $ContextMenu)
$CutMenuItem = GUICtrlCreateMenuItem("&Cut", $ContextMenu)
$CopyMenuItem = GUICtrlCreateMenuItem("&Copy", $ContextMenu)
$PasteMenuItem = GUICtrlCreateMenuItem("&Paste", $ContextMenu)
$DeleteMenuItem = GUICtrlCreateMenuItem("&Delete", $ContextMenu)
GUICtrlCreateMenuItem("", $ContextMenu)
$SelectAllMenuItem = GUICtrlCreateMenuItem("&Select all", $ContextMenu)
GUICtrlCreateMenuItem("", $ContextMenu)
$InsertDateMenuItem = GUICtrlCreateMenuItem("&Insert Date and Time", $ContextMenu)

GUISetState(@SW_SHOW)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        ; toggle our context menu on / off
        Case $checkBox
            If BitAND(GUICtrlRead($checkBox), $GUI_CHECKED) = $GUI_CHECKED Then
                _WinAPI_SetWindowLong(GUICtrlGetHandle($editBox), $GWL_WNDPROC, DllCallbackGetPtr($w_editBoxProcNew))

Excellent demonstration of example, killing the following sentence:

"Note: You can not create context menus for controls That Already have context menus system, ie input or edit controls."

The final must be in the following sequence:

Case $GUI_EVENT_CLOSE
            ;!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
            ;!! we must free the callback before exit !!
            _WinAPI_SetWindowLong(GUICtrlGetHandle($editBox), $GWL_WNDPROC, $w_editBoxProcOld)
            DllCallbackFree($w_editBoxProcNew)
            Exit

***** stars!

Regards,

João Carlos.

Consider updated.

JScript thanks for your kind words.

I made something similar nearly 2 years ago.

I deactivated unnecessary things for demonstration.

I will have a look at your solution. Thanks for sharing!
