A Menu Button

.

CMenuButton in action

Download Source


In my latest project, File Axe, I decided I wanted something very like the
little arrow buttons that one can find in DevStudio’s Tools|Customize…
property sheet, Tools tab. The little button on the right of the edit control
for “Arguments:” to be precise. So, after a quick browse on codeguru
reveled nothing, I decide it would not be hard to make, and I could wrap
Randy More’s cool way of using the TrackPopupMenu in immediate mode. I have a
feeling I will be using it more you see. (:


Uses code from…


The niffy way of using the menu in immediate mode is (directly) from Using CMenu::TrackPopupMenu as an Immediate Function – Randy More,
General owner draw format from Flat owner drawn buttons – Girish Bharadwaj,
and the idea for drawing the arrow from PushButton with bitmap & text – Michael Santoro


UNICODE?


I have no way to test if this will work with UNICODE, however it SHOULD. (:

This was compiled with VC5 and MFC4.2. Tested on Win95 OSR2 (no IE4
integration). This code should compile cleanly under warning level 4.


To Use:


Simply include “MenuButton.h” and “MenuButton.cpp” in your
project, and include “MenuButton.h” in whatever file you wish to use it in
(“stdafx.h” mayhaps).



Then in the dialog editor, make a normal button, a suggested size is 12×14. The
little arrow gfx will be centered in the button in any case. Make a handler for
a button click, and copy the sample usage code to there, then of course modify to suit your needs.

A way to use CMenuButton… (aka the sample usage code)


// -[Feral]---------------------------------------------------------------
// pop up a menu, and add pre defined text to the edit ctrl.
void CPP_Split::OnBUTTONNameFormatOptions()
{
    // -[Feral]-----------------------------------------------------------
    // Vars and Assignment
    CEdit *pEdit = (CEdit*)GetDlgItem(IDC_EDIT_NameFormat);


    // -[Feral]-----------------------------------------------------------
    // popup a menu and let the user make a selection...
    DWORD dwSelectionMade = m_menubuttonNameFormatOptions.DoSingleClick(IDM_NameFormatOptions);

    // -[Feral]-----------------------------------------------------------
    // Do something with the selection
    // -------------------------------------------------------------------
    // The value of dwSelectionMade is the id of the command selected or 0 if no selection was made
    switch(dwSelectionMade)
    {
        default:                        // Do nothing (No selection)
            break;
        case `Menu Resource ID`:
            pEdit->ReplaceSel(_T("`Text to add at cursor, or replace selection with`") );
            break;
// Example case...
//Tip: Open the resource file (<apname>.rc) and copy your menu from there... much easier.
        case ID_PREDEFINEDPOPUP_SAMPLE1FILENAME1XEXTSPLITPIECE:       // "Sample #&1: Filename.1_X.Ext.SplitPiece",
            pEdit->ReplaceSel(_T("<File>.<1_X>.<Ext>.SplitPiece") );
            break;
    }

    // -[Feral]-----------------------------------------------------------
    // Clean Up and Return
}


Questions, comments, bug fixes (gasp! (: ) and whatever else comes to mind are always welcome!


Happy Coding!
