check mark in menu

**willc0de4food** · 08-03-2005

hey, i know how to get a menuitem checked to start off with...but how do i add a check next to an item in the menu while the program is running? my brain is failing as i type this, but like in your menu, if you clicked on a property that sets something, such as bold (random example), then it would put a checkmark next to it to indicated its selected / clicked / active / whatever.

how do i set the check mark when the menuitem it clicked while the program is running? lol thanks

....how bout the CheckMenuItem Function ?

*slaps forehead*
but some usage is always nice. anyone have that?

also - the default font for static controls (created with CreateWindowEx) its like..big and kinda bold. is that changeable? then lastly, if i have a static control (again, created with CreateWindowEx) and i dont add any text when i create it, can i add text when something happens? if so, how?

thanks guys.

If you want to add text or modify text of a static control and you don't want to keep it's handle in memory you must give it an id so you can retrieve it with GetDlgItem, send a WM_SETTEXT message to the control. To set the font of a static control send it a WM_SETFONT message and to make it easy you are usually safe using GetStockObject ( DEFAULT_GUI_FONT ) ;

For menu stuff you can also use InsertMenuItem which is much more flexible, MENUITEMINFO .fState should have MF_CHECKED set. To modify the state and information of a menu item call SetMenuItemInfo.

Code:

MENUITEMINFO itemInfo ;
itemInfo.cbSize = sizeof ( MENUITEMINFO ) ;
itemInfo.fMask = MIIM_ID | MIIM_STATE | MIIM_STRING | MIIM_FTYPE ;
itemInfo.fType = MFT_STRING ;
itemInfo.fState = MF_ENABLED | MF_CHECKED ;
itemInfo.wID = IDM_MENUITEM1 ;
itemInfo.dwTypeData = "Item String" ;
InsertMenuItem (
					hMenu,
					0,
					TRUE,
					&itemInfo
				) ;

mm...the menu code, adds "Item String" in the first spot of the menu, so then it jumps in the "File" menu's position and moves everything down.

i just want to add a check mark, lol here's the code for my menu:

Code:

ID_TEMPCONV_MENU MENU
BEGIN
     POPUP "&File"
     BEGIN
          MENUITEM "C&lear", ID_FILE_CLEAR
          MENUITEM SEPARATOR
          MENUITEM "&Close", ID_FILE_CLOSE
     END
     POPUP "&Units"
     BEGIN
          POPUP "&Fahrenheit"
          BEGIN
               MENUITEM "to Cel&sius", ID_UNITS_FTOC
               MENUITEM "to Kel&vin", ID_UNITS_FTOK
          END
          POPUP "&Celcius"
          BEGIN
               MENUITEM "to F&ahrenheit", ID_UNITS_CTOF
               MENUITEM "to Kel&vin", ID_UNITS_CTOK
          END
          POPUP "&Kelvin"
          BEGIN
               MENUITEM "to F&ahrenheit", ID_UNITS_KTOF
               MENUITEM "to Cel&sius", ID_UNITS_KTOC
          END
     END
     POPUP "&Help"
     BEGIN
          MENUITEM "&About...", ID_HELP_ABOUT
     END
END

i just want to add a check mark to the "to ..." part, but if theres a check mark somewhere else, it has to go away.

thanks for the help!
i'm prly staring at the answer but dont know it..*shrug* any more help? its greatly appreciated

thanks

also - this is the stuff with the fonts i was talking about. the first screeny is of the program i made in VB .Net, the second the program made in C. i would like the C program's fonts to be like those of the program in VB .Net and am hopeing its not very complicated? :-[ thanks^2!

Use CheckMenuItem like so:-

Code:

CheckMenuItem(hmenu, ID_UNITS_FTOC, MF_CHECKED);

Use MF_UNCHECKED to remove check.

For default GUI font, as in your VB.NET example:-

Code:

HFONT hfont;

hfont = GetStockObject(DEFAULT_GUI_FONT);
// Send this message to each control
SendMessage(hwnd, WM_SETFONT, 0, (LPARAM)hfont);

And when you want to change the text displayed by a control:-

Code:

SendMessage(hwnd, WM_SETTEXT, 0, (LPARAM)"Hello");

idk why..but uh, checkmenuitem doesn't check the menu item. lol

hfont doesn't change the font. maybe i can create one? like 10 pt times new roman (weight) thin ?

thanks

i found that out...along with SendDlgItemMessage()

also, this code does nothing

Code:

              HFONT hfont;
              int nHeight = 10, nWidth, nEscapement = 0, nOrientation = 0, fnWeight = 100;
              hfont = CreateFont (
                      nHeight,                 // height of font
                      0,                       // average character width
                      nEscapement,             // angle of escapement
                      nOrientation,            // base-line orientation angle
                      fnWeight,                // font weight
                      FALSE,                   // italic attribute option
                      FALSE,                   // underline attribute option
                      FALSE,                   // strikeout attribute option
                      DEFAULT_CHARSET,         // character set identifier
                      OUT_DEFAULT_PRECIS,      // output precision
                      CLIP_DEFAULT_PRECIS,     // clipping precision
                      DEFAULT_QUALITY,         // output quality
                      DEFAULT_PITCH,           // pitch and family
                      null               // typeface name
                      );
              // Send this message to each control
              SendMessage(hwnd, WM_SETFONT, 0, (LPARAM)hfont);
              DeleteObject(hfont);

*is clueless*

They should work (I use them all on a regular basis), how are you using CheckMenuItem?

Try using this:-

Code:

CheckMenuItem(GetMenu(hwnd), ID_UNITS_FTOC, MF_CHECKED);

Just to make sure that you're passing the window's menu handle.

And where I say "send this message to each control", you have to ensure that you're changing the window handle for each control, i.e.:-

Code:

SendMessage(hwndEdit1, WM_SETFONT, 0, (LPARAM)hfont);
SendMessage(hwndEdit2, WM_SETFONT, 0, (LPARAM)hfont);
...

mm..i'm giving up for now and going to bed so i can try working on it later because i think that may be prohibiting it from working right. but i still couldn't get things to work right.

haha...yea..oops. i was putting the code for FTOC in the case for FTOK..*slaps forehead*
..ouch..
anyways, the font thing - i'm still clueless about that

i'll upload my code in a min. as a zip file (for the .c, .h, and .rc files) but the location will be: http://www.angelfire.com/linux/shibb...converter.html

thanks for the help

also..whats the easiest way to keep track of which menu items are checked? i dont think it would be good coding to uncheck every menu item when you check one..?
