Modal and non-modal windows

Introduction to the modal and non-modal windows in WinCE

I. Create

Create a non-modal window

Code
Fivelistwnd * Five = New Fivelistwnd ();
Five -> Create ( 0 , 0 , 400 , 600 , M_hwnd, 0 , 0 );
Five -> Setbgcolor (RGB ( 255 , 255 , 255 ))
Five -> Show ();

Create a modal window

 

Code
1 Fivelistwnd five;
2 Five. Create ( 0 , 0 , 400 , 600 , M_hwnd, 0 , 0 );
3 Five. setbgcolor (RGB ( 255 , 255 , 255 ))
4 Five. domodal ();

Ii. Differences

1. After the mode window is opened, the input focus is always maintained. You cannot switch to the parent window unless the window is closed.
In the non-modal window, you can move the focus to the parent window. You can use show (false) to switch the window)

Second, we can see from the above that the non-modal window must be new

Third, the method for closing the window is different.

To use cwnd: destroywindow for a non-modal window

Use cdialog :: enddialog in the modal window

Because the non-modal window is new, delete is required at last. Although destroywindow (), the window instance is not destructed.

Iii. Note

Create ( 0 , 0 , 400 , 600 , M_hwnd, 0 , 0 );

M_hwnd in is the handle of the parent window. In the five window, that is, the subwindow, you can use getparent () to obtain the handle of its parent window.
