Introduction

CTrueColorToolBar is a real true color toolbar. Implementation of the class is very very easy. The particularity of this toolbar is the auto detection of the mask color with the DIB section of the first pixel of bitmap toolbar.

Steps to use

Create dummy 16 color toolbar in VC with the number of buttons and final size you need.
In your favorite painter, make 3 other true color toolbar bitmaps for state buttons (Normal, Hot, Disabled) based on the first one.
Import your new true color toolbars in VC.
Create new CTrueColorToolBar toolbar with the sample implementation of normal toolbar.
Call LoadTrueColorToolBar function with your 3 true color toolbar bitmaps and the size of a button.
That's it!

Example

//In Mainframe.h #define TOOLBAR_DRAW_BUTTON_WIDTH 24 #include "TrueColorToolBar.h" class CMainFrame : public CFrameWnd { CTrueColorToolBar m_ToolBarDrawLeft; } //In Mainframe.cpp int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (CFrameWnd::OnCreate(lpCreateStruct) == -1) return -1; if (!m_ToolBarDrawLeft.Create(this, WS_CHILD | WS_VISIBLE | CBRS_LEFT | CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) || !m_ToolBarDrawLeft.LoadToolBar(IDR_TOOLBAR_DRAW)) { TRACE0("Failed to create toolbar/n"); return -1; //Failed to create } //Add bitmap to toolbar m_ToolBarDrawLeft.LoadTrueColorToolBar( TOOLBAR_DRAW_BUTTON_WIDTH, IDB_TOOLBAR_DRAW, IDB_TOOLBAR_DRAW_HOT, IDB_TOOLBAR_DRAW_DISABLED); //Add DropDown Button m_ToolBarDrawLeft.AddDropDownButton(this, ID_BUTTON1, IDR_MENU1); return 0; }

Conclusion

Note also that in the function LoadTrueColorToolBar, if you omit the last parameter for disabled toolbar, you will get a default embossed disabled toolbar. Enjoy!
