Desktop-as-a-Service Designed for Any Cloud ? Nutanix Frame
Many programmers are interesting in splitter that using in dialogbox, so do I.
Anyway, Lin's splitter is very good and easy to use, but it has some limitation, such as: 1) do not support more than one pane on one side of the splitter; 2) do not support vertical split; 3) no dragging restriction. Fortunately, it is not very hard to add these features.
Here is the project I'v made, it was built with VC5.0 & MFC version 4.21.
Two classes are provided: CxSplitterWnd & CySplitterWnd, to use them, follow the steps below:
1. Add the source files to your own project, they are xySplitterWnd.h & xySplitterWnd.cpp .
2. Create an picture control in the dialog resource, this control will act as a splitter afterward.
Set the type as Frame, move it to the appropriate position, then give it an ID, such as IDC_XBAR1. One picture control for one splitter, you can make any number of splitters as you like.
3. Declare the objects of CxSplitterWnd/CySplitterWnd in your dialog class.
Of course, you should include xySplitterWnd.h first.
CxSplitterWnd m_xSplitter1, m_xSplitter2; CySplitterWnd m_ySplitter;
4. Initiate the splitter objects in the InitDialog function.
m_xSplitter1.BindWithControl(this, IDC_XBAR1); // bind the splitter object to the puppet control m_xSplitter1.SetMinWidth(10, 50); // set the minimum width of the left/right pane m_xSplitter1.AttachAsRightPane(IDC_LEFTPANE1); // attach a control within the same dialogbox as a pane of the splitter m_xSplitter1.AttachAsRightPane(IDC_YBAR); // you can even attach another splitter as a pane m_xSplitter1.AttachAsRightPane(IDC_LEFTPANE2); m_xSplitter1.RecalcLayout();
5. Un-bind the splitter object with the puppet control when dialogbox is going to close.
This step can be omitted when you do not want to re-use the splitter object.
Just as Lin's work, there is a message "WM_SPLITTER_MOVED" that generated by the splitter bar whenever the splitter is dragged then dropped. If you want to do something special when the splitter is repositioned, then provide a message handler for this message.
