As shown in figure, I want to be in based on the MFC dialog box is a slick implementation of a floating window can be docked, the implementation situation now is: in the main dialog call derived from CFrameWndEx MainFrame class and create, and then the main dialog box, MainFrame, at the same time

At this time should be the main dialog to hide or stick the MainFrame to the main dialog box? Could you tell me how to do this? For dialog also do other controls such as operation,
And close this program will be submitted to the many wrong, what should I do?

Bosses implemented this feature? Can you give a source under study?

This is my last post, reply, so also open a new post

CodePudding user response:

Or I would have this kind of want to based on the dialog box to add floating window can be wrong?

CodePudding user response:

The parent window is CMyframe dialog box, the size is smaller than the dialog box!

CodePudding user response:

refer to the second floor schlafenhamster response:

is the parent window in the CMyframe dialog box, the size than the dialog box!

 
if (! M_mainFrame. Create (NULL, _T (" TEST "), WS_OVERLAPPEDWINDOW, CRect (0, 0, 100, 100))) 
{
TRACE0 (" failed to create output window/n "); 
return FALSE; 
} 

Could you tell me the CMyframe Create how to Create a child window?

CodePudding user response:

M_pMyFrame=new CFrameWnd;
M_pMyFrame - & gt; Create (0, "", WS_CHILD, rc, this);

CodePudding user response:

reference 4 floor schlafenhamster response:

m_pMyFrame=new CFrameWnd;
M_pMyFrame - & gt; Create (0, "", WS_CHILD, rc, this);

 
CRect rectDlg; 
GetClientRect (rectDlg); 
MainFrame * m_pMyFrame=new MainFrame; 
M_pMyFrame - & gt; Create (0, _T (" "), WS_CHILD, rectDlg, this); 
M_pMyFrame - & gt; ShowWindow (SW_SHOW); 

After I such a success


But when I drag a window when the second program interrupt (drag, double-click on the dock, drag again, to stop this normal; Only drag then drag once again interrupted), bosses look


Then the debugging information is
