Has anyone ever wondered how to dock a toolbar inside a splitter pane? Normally, you cannot do that, but you can alter your splitter pane so that it will look just like you placed a toolbar on one of its sides. The trick is to create a two-pane splitter where your initial pane was; but not just any splitter, we will use our own, which does not allow resizing, and has different border settings. There is one additional view to create, and we will derive a class from
CFormView since features provided by this class are closer to our goal.
First goes the custom splitter window:
// class definition
class CSmartSplitterWnd : public CSplitterWnd
// class implementation
// put your own values here, to make the splitter fit your needs
// do not allow caller to see mouse hits
Next, we must create a simple
CFormView using the resource editor and
ClassWizard. You can add any controls to your form view, but you must keep in mind that handling the
WM_SIZE message may help you improve the look of your view. There are several ways to update your buttons and other controls inside the view; you may need to implement one of them to update, enable or disable the controls.
The last step is to create the splitter itself and the views. The code below matches a SDI application that accommodates the code above inside a splitter pane, but you can easily adjust it to fit your needs.
First, add a member to the
CMainFrame class of type
class CMainFrame: public CFrameWnd
OnCreateClient member of the
CMainFrame class, add code to create the splitter inside the right pane:
// create the splitter window
if (!m_barSplitter.CreateStatic(&m_parentSplitter, 2, 1,
m_parentSplitter.IdFromRowCol(1, 0))) return false;
// create the views
m_barSplitter.CreateView(0, 0, RUNTIME_CLASS(CBarView), CSize(0, 0), pContext);
m_barSplitter.CreateView(1, 0, RUNTIME_CLASS(CTheView), CSize(0, 0), pContext);
// then set heights
The code is quite easy to follow and change to meet your needs, but if you need assistance, contact me. Also please send me bugs or updates, to keep this solution up-to-date. For more details on the sample application, contact me.
