A skinned button class with clipping region, tooltip and mouse tracking

Sample Image - sample.gif

With this class you can easily give a skin to your buttons in few steps:

  1. Add xSkinButton.cpp and xSkinButton.h to the project.
  2. Include xSkinButton.h in the header file where the controls are defined
  3. Create (or edit) a member variable for each button you want to customize as CxSkinButton. If the Class Wizard doesn't show the CxSkinButton type, select CButton and then edit the code manually.
  4. Add the bitmap resource for the buttons:
    • NORMAL bitmap: default button image.
    • DOWN bitmap: pushed button image.
    • OVER bitmap:(optional) image to shown when the mouse is over the button. If NULL, NORMAL bitmap will be used.
    • DISABLED bitmap: (optional) image for the disabled state. If NULL, NORMAL bitmap will be used.
    • FOCUS bitmap: (optional) image for the focused state. If NULL, NORMAL bitmap will be used.
    • MASK bitmap: (optional) clipping region. If you don't use the MASK, the button will be a rectangular owner-draw control. The default transparent color is RGB(255,255,255).
  5. In the window initialization add the CxSkinButton methods:
    BOOL CxSkinButtonDemoDlg::OnInitDialog()
    {
    //    ...
        m_btn1.SetTextColor(RGB(255,0,0));
        m_btn1.SetToolTipText("Button1");
        m_btn1.SetSkin(IDB_B1NORM,IDB_B1DOWN,IDB_B1OVER,IDB_B1GRAY,
                           0,IDB_B1MASK,0,0,0);
    //    ...

    The SetTextColor and SetToolTipText are self explaining; SetSkin is:

    void CxSkinButton::SetSkin(UINT normal,UINT down,UINT over, 
                               UINT disabled, UINT focus,UINT mask, 
                               short drawmode, short border, 
                               short margin)
    • normal, down, over, disabled, focus, mask = bitmap resource IDs
    • drawmode = if mask is not NULL, this should be 0 (normal); else you can try 1 (stretch) or 2 (tiled).
    • border = if mask is not NULL or is not rectangular, this should be 0; else you can try 1 to draw the standard 3D border around the button.
    • margin = if mask is not NULL or is not rectangular, this should be 0; else you can try to change this value to draw a dotted rectangle over the button when the control has the focus.

Remarks

  • The BS_OWNERDRAW style is added automatically, you don't need to set the "Owner draw" property in the resource editor.
  • only NORMAL and DOWN bitmaps are essential; OVER bitmap is a plus.
  • DISABLED bitmap is not necessary if the button is always enabled. You can also use the button text (automatically etched) to show the disabled state.
  • MASK bitmap is not necessary if the button is rectangular.
  • for rectangular buttons you should set the margin parameter greater than 0 (4 is a good choice), or use the FOCUS bitmap.
  • for rectangular buttons you can use 'flat' bitmaps and set the border parameter to 1. In this situation, NORMAL and DOWN bitmaps can also share the same resource.
