Two different views in a splitter window, one doc (SDI)
-
The summary of my problem is this: two different views in a splitter window, one doc (SDI). I want to access the document's members from both views. I've created an application with a CSplitterWnd in my MainFrame. I've created the two views using m_wndSplitter.CreateView(....); That displays fine. Wonderful. I've got a variable in my doc class, int lookie. It's public. My class names are as follows: CThingApp -> the app class CThingDoc -> the doc class CThingControlView -> the form view containing the controls CThingDisplayView -> the graphical view displaying the data CMainFrame -> frame class CThingControlView was created with the whole project. I added CThingDisplayView. So I changed the code in CThingApp:InitInstance() to look like this: //////////////////////////// CSingleDocTemplate* pDocControlTemplate; pDocControlTemplate = new CSingleDocTemplate( IDR_MAINFRAME, RUNTIME_CLASS(CThingDoc), RUNTIME_CLASS(CMainFrame), // main SDI frame window RUNTIME_CLASS(CThingControlView)); AddDocTemplate(pDocControlTemplate); //////////////////////////// This seems to work. Here's where my confusion sets in. I *thought* I now need to add the following code immediately beneath the above code: //////////////////////////// CSingleDocTemplate* pDocDisplayTemplate; pDocDisplayTemplate = new CSingleDocTemplate( IDR_MAINFRAME, RUNTIME_CLASS(CThingDoc), RUNTIME_CLASS(CMainFrame), // main SDI frame window RUNTIME_CLASS(CThingDisplayView)); AddDocTemplate(pDocDisplayTemplate); //////////////////////////// I now believe that to be a false assumption because, upon building, the application displays a funny little window with the title new and what appears to be a list of options. There are two options with exactly the same text (which appears to be shortenings of my project name). If I select either one the application then starts. Because this was incorrect behavior, I commented out the second document template code and tried several different ways of just *accessing* the data in CThingDoc from CThingDisplayView. Nothing's working. I'm sure there is a simple solution to this. Something that my examples neglect to tell me or that I'm just not noticing.

Here you have a goog tutuorial about the splinter window : http://www.codeproject.com/splitter/splitterwindowtutorial.asp[^] I do not think you need to recreate a template for the second view...

Stop fiddling around with the DocumentTemplate! You'll eventually destroy your application and need to start over! Create the splitter with its views a s described in the other post. Then, to access the document, you need to use
CThingDoc* pDoc = dynamic_cast(GetDocument());
if()
{
//do it
}in your CThingDisplayView and CThingControlView.
Failure is not an option - it's built right in.

For splitter windows, you only need one
CSingleDocTemplateobject that is created like:CSingleDocTemplate* pDocControlTemplate;
pDocControlTemplate = new CSingleDocTemplate(
IDR_MAINFRAME,
RUNTIME_CLASS(CThingDoc),
RUNTIME_CLASS(CMainFrame), // main SDI frame window
RUNTIME_CLASS(NULL));
AddDocTemplate(pDocControlTemplate);
