Thread: Pop up menues

How do you create a pop-up menu? (those who usually appear when you right-click).
Is it the same kind of menu that you use under the caption-border?

<edit>
Another question:
I have a dialog with one text-edit and two buttons. I'm using DialogBoxParam to create it. The first time it is created, the text-edit is selected (which is exactly what I want).
But when I close it and later create another one, it is not selected.
Is there a function (or message to send) that selects a control in a dialog?
I've tried ShowWindow() and some other, but they didn't work.
</edit>

Use TrackPopupMenu() for the popup.....manipulate WM_INITDIALOG for the focus.....ala;


::for msvc++6, but you can edit the resource script and header to get rid of any non crucial stuff::

Code:

#include <windows.h>
#include "resource.h"

BOOL CALLBACK DialogProc2(HWND hwndDlg,UINT uMsg,WPARAM wParam,
		 LPARAM lParam){

	HWND hEdit;

	switch(uMsg){
	case WM_INITDIALOG:
		hEdit = GetDlgItem(hwndDlg,IDC_EDIT2);//get handle of 2nd edit
		SetFocus(hEdit);//set its focus
		return 0;//return 0 to overide system setting default focus
	case WM_CLOSE:
		EndDialog(hwndDlg,0);
		return 1;
	}


return 0;
}


BOOL CALLBACK DialogProc(HWND hwndDlg,UINT uMsg,WPARAM wParam,
		 LPARAM lParam){
	
	static HMENU hMenu;
	POINT point;

	switch(uMsg){
	case WM_INITDIALOG:
		hMenu = LoadMenu(GetModuleHandle(NULL),//Load Menu
			MAKEINTRESOURCE(IDR_MENU1));
		hMenu = GetSubMenu(hMenu,0);//Get Sub Menu
		return 1;
	case WM_RBUTTONDOWN:
		point.x = LOWORD(lParam);//Get cursor Pos
		point.y = HIWORD(lParam);
		TrackPopupMenu(hMenu,TPM_LEFTALIGN | TPM_RIGHTBUTTON,
			point.x,point.y,NULL,hwndDlg,NULL);//Create popup
		return 1;
	case WM_CLOSE:
		DestroyMenu(hMenu);
		EndDialog(hwndDlg,0);
		return 1;
	case WM_COMMAND:
		if(LOWORD(wParam == WM_POPUPCLICKED)){
			MessageBox(hwndDlg,"ClickMe!!",NULL,MB_OK);//was popup clicked
			return 1;
		}
		else if(LOWORD(wParam == IDOK)){
			DialogBoxParam(GetModuleHandle(NULL),MAKEINTRESOURCE(IDD_DIALOG2),
				hwndDlg,DialogProc2,NULL);//Launch 2nd dialog
			return 1;
		}
	}


return 0;
}


int WINAPI WinMain(HINSTANCE hInst,HINSTANCE,LPSTR,int){


	DialogBoxParam(hInst,MAKEINTRESOURCE(IDD_DIALOG1),
		HWND_DESKTOP,DialogProc,NULL);

	

return 0;
}

Thanks!

I have some problems with the popup menu:

1) When the popup is created, it is located relative to the upper left of the screen, not the upper left of my window.
How can I correct this? Can I somehow recieve the position of the window so I can calculate the right point? Or is there some easier way?

2) The popup can only be created when right clicking directly on the window, not any of it's controls. I want it to appear only when right clicking on a specific list I have. How can I do this?

<edit>
I tried using the WM_NOTIFYPARENT message, but it is never sent (I checked using a MessageBox directly under it).
But I have the LBS_NOTIFY flag set on the control...
</edit>

3) This is not so important, but can you disable that you can select a menu-option with the right mouse button?

1)

Code:

POINT position;
GetCursorPos(&pos);
TrackPopupMenu(.... position.x, position.y, .....);

2)

Wherever the WM_RBUTTONDOWN is handled is where it will show up. You handled it in the main window apparently. Your list has to handle it. If you're using the ListBox common control there is a message you'll have to handle that comes from the control but I don't know what it is off hand

This is the popup-menu part of my main message handler.
Is this wrong?

Code:

case WM_PARENTNOTIFY:
   switch(LOWORD(wParam))
   {
      case WM_RBUTTONDOWN:
         GetCursorPos(&TempPosition);
         TrackPopupMenu(ListPopupMenu, TPM_LEFTALIGN | TPM_RIGHTBUTTON, TempPosition.x, TempPosition.y, NULL, Handle, NULL);
         break;
   }
   break;

<edit>
I can catch the LBN_DBLCLK message just fine,
but there doesn't seem to be a message for a
right click...
</edit>

Found it.
Its WM_CONTEXTMENU.
