When I wanted a quick and nice header for my SDI project I could not find any, so I made my own. Some of the code is for beginners. It is not made for learning, but just for saving some time. There are some comments on the code, but almost all of it should be crystal clear, even for beginners. The header supports different colors on text, text shadows, and background, change of font size and type, change of placement of the text in the header. It does also have a gradient effect on the background. In the new update I've implemented support for adding pictures in the back of the text. I've also included a MDI project which include a CView class that with the same toolbar. Please see history for other changes done.
The CHeaderToolbar is inherit its functions from CToolBar, and it is assumed as regular toolbar like the default "new, open, save"-toolbar in SDI/MDI projects.
When you create a toolbar it is really important that you call the SetDrawRect(Rect) function. The creation process for a default header toolbar is like this:
CRect Size;
Size.SetRect(0,0,0,30);
if (!m_headerdefault.CreateEx(this, TBSTYLE_TRANSPARENT ,
WS_CHILD | WS_VISIBLE | CBRS_TOP, Size))
{
TRACE0("Failed to create header\n");
}
//The rect is transparent, until you set the drawrect...
m_headerdefault.SetDrawRect(Size);The Size rect is only used to set the height on creation. If the creation is successful you will get a header with default colors. To manipulate the other settings you can use these functions: //Background void SetDrawRect(CRect Rect); //Required, or else the toolbar is transparent void SetGradient(BOOL Activate); //TRUE OR FALSE void SetGradientStartColor(COLORREF GradientStart); //This also sets the default color when gradient is off void SetGradientEndColor(COLORREF GradientEnd); //End gradient color //Border void SetRemoveBorder(BOOL OnOff); BOOL GetRemoveBorder(); //Text void SetWindowText(CString InputText); //Outputtext on screen void GetWindowText(CString &OutputText); //Returns current text void SetFont(CString FontName); //Set the font name (as text) void SetFontSize(int NewSize); //Set the point-size void SetTextCol(COLORREF Col); //Set the text color void SetTextShadowCol(COLORREF Col); //Sets the color of the shadow void SetPlaceMent(int Place); //DT_LEFT, DT_CENTER and DT_RIGHT is available //options. (MSDN: CDC -> DrawText())Each time you use the different functions to change layout, the header refreshes. If you want to change more options and stop the redrawing use the
SetRedraw(FALSE) to the toolbar, and then SetRedraw() to enable redrawing again.
In this version I've got a great solution for getting rid of the border around each toolbar. I want to say thanks to Christian Wieninger at codeguru.com for telling me. As default the border is drawn, to remove it you can use SetRemoveBorder(TRUE). Here is an example of how it looks like:
At the left the border is drawn, at the right it is gone. At the bottom there is a picture included. For adding a picture check out these functions:
//Picture loading void LoadBackgroundPicture(CString Path); //Load the picture from any locations at your harddrive void SetStrech(BOOL OnOff); //Stretch to fit on/off void SetPicturePlaceMent(int Place); //Placement of the picture (DT_LEFT, DT_CENTER and DT_RIGHT) void SetVAlign(BOOL OnOff); //Vertical align picture to always fit on/off BOOL GetStrech(); //Returns the status of strech.
When I made the MDI example I got a request on how to implement a toolbar in a CView window. In the example I've added the HeaderToolbar to each of the MDI views and on the MainFrm.
