MFC split view size problem-CodePudding

Creates a static view
The code below

 BOOL CMainFrame: : OnCreateClient (LPCREATESTRUCT LPCS, CCreateContext * pContext) 
{
//TODO: add in this dedicated code and/or call the base class 

//create a static window, divided into two columns, one line 
if (! M_splitter. CreateStatic (this, 1, 2)) 
return FALSE; 

If (m_splitter1. CreateStatic (& amp; M_splitter, 2, 1, WS_CHILD | WS_VISIBLE, m_splitter. IdFromRowCol (0, 0))==NULL) 
return FALSE; 
//will FormView1 link to the second column column object row 0 0 
If (m_splitter1. CreateView (0, 0, RUNTIME_CLASS (FormView1), CSize (400, 400), pContext)==NULL) 
return FALSE; 
//will FormView2 class 1 row of links to the second column object column 0 
M_splitter1. CreateView (1, 0, RUNTIME_CLASS (FormView2), CSize (400, 200), pContext); 
//will COTDRView link line 1 0 column pane 
M_splitter. CreateView (0, 1, RUNTIME_CLASS (RightView), CSize (100, 600), pContext); 
return TRUE; 
}

But the view is always the right to occupy all the size of the diagram below:

So overloaded onsize to set the view size, but would have been an error

, the companion code, there is no problem, so you also want to give a great god some directions!

OnSize need to judge whether the HWND effective first:

 if (NULL! .=m_splitwnd GetSafeHwnd ()) 
{
CRect the rect. 
GetClientRect (... ); 
M_splitwnd. SetRowInfo (); 
M_splitwnd. SetColumnInfo (); 
M_splitwnd. RecalcLayout (); 
}

Collapsed in the pop-up dialog box, press the corresponding button to enter debugging press Alt + 7 key to view the Call Stack, namely "the Call Stack" from the inside to the following out of from the inner to outer function Call history, double-click a row to the cursor to the Call of the source code or assembly instruction, double-click on the next line when don't understand, until can understand,

If (IsWindow (m_Splitter m_hWnd))

CodePudding user response:

3 and 5 floor thought because OnSize will perform before OnCreateClient so, right at the first time into the OnSize splitter is empty has not been created, the need for judgment, but 3 and 5 floor method I tried no effect into execution, so I'm splitter. The CreateStatic after adding tags m_bIsSplitterCreate=TRUE, the first in the OnSize judgment if (m_bIsSplitterCreate==TRUE)
