Bitmaps

[Martian Man]

How do I make a new bitmap in the secondary menu with the new, open, save, and so on pictures?

Are you talking about a toolbar, where you have additional icons for doing common tasks?

Uh!?

[Martian Man]

In response to Osito, yes that toolbar. Please respond. Thanks!

I had a tough time finding examples of that. I think maybe the Microsoft suite of tools has a wizard for toolbars, so not many people do it from code? I did eventually get it to work. Here is an example. It is called from within the WM_CREATE case. It is right after the main window is created (also after InitCommonControls() is called, which requires #include <commctrl.h>).

I have TOOLBAR_NUMBER_OF_BUTTONS and all of the indices used in the tbb array defined in my .h file to make it easier to rearrange the buttons.

You will also need a line like this in your resource file: IDB_TB_BITMAP BITMAP "buttons.bmp" and a #define for the IDB_TB_BITMAP. The bitmap is just a bunch of buttons side by side. In my case it is 416x32 pixels, because I have 13 buttons that are 32x32.

I think there's something else too, but it escapes me ATM.

void CreateToolBar(HWND hwnd)
{
TBBUTTON tbb[TOOLBAR_NUMBER_OF_BUTTONS];
TBADDBITMAP new_buttons;
int i;

// create window
g_hToolBar = CreateWindowEx(0,TOOLBARCLASSNAME,NULL,WS_CHILD|WS_VISIBLE|WS_BORDER,0,0,0,0,hwnd,(HMENU)ID_TOOLBAR,g_hInst,NULL);

// tell it the size of the structure
SendMessage(g_hToolBar, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);

// set bitmap size
SendMessage(g_hToolBar,TB_SETBITMAPSIZE,0,MAKELONG(32,32));

// load bitmaps
new_buttons.hInst = g_hInst;
new_buttons.nID=IDB_TB_BITMAP;
SendMessage(g_hToolBar,TB_ADDBITMAP,TOOLBAR_NUMBER_OF_BITMAPS,(LPARAM)&new_buttons);

// clear button structures and set info
ZeroMemory(tbb, sizeof(tbb));

// fill with separators by default
for (i=0;i<TOOLBAR_NUMBER_OF_BUTTONS;i++) {tbb[i].fsStyle = TBSTYLE_SEP;}

I forgot this, in your main case statement. I also have a statusbar - if you don't you'll have to rewrite it a little to get rid of that stuff.

  case WM_SIZE:
  {
     RECT rectClient, rectStatus, rectTool;
     UINT uToolHeight, uStatusHeight, uClientAlreaHeight, uStatusSegmentWidth;

     SendMessage(g_hToolBar, TB_AUTOSIZE, 0, 0);
     SendMessage(g_hStatusBar, WM_SIZE, 0, 0);

     GetClientRect(hwnd, &rectClient);
     GetWindowRect(g_hStatusBar, &rectStatus);
     GetWindowRect(g_hToolBar, &rectTool);

     uToolHeight = rectTool.bottom - rectTool.top;
     uStatusHeight = rectStatus.bottom - rectStatus.top;
     uClientAlreaHeight = rectClient.bottom;

     uStatusSegmentWidth = (rectClient.right-rectClient.left)/STATUSBAR_NUMBER_OF_SEGMENTS;
     for(i=0;i<STATUSBAR_NUMBER_OF_SEGMENTS-1;i++) {statusbar_width[i]=uStatusSegmentWidth*(i+1);}
     statusbar_width[STATUSBAR_NUMBER_OF_SEGMENTS-1]=-1;

     MoveWindow(GetDlgItem(hwnd, IDC_MAIN_TEXT), 0, uToolHeight, rectClient.right, uClientAlreaHeight - uStatusHeight - uToolHeight, TRUE);
     SendMessage(g_hStatusBar,SB_SETPARTS,(WPARAM)STATUSBAR_NUMBER_OF_SEGMENTS,(LPARAM)statusbar_width);
  }
