1. Overview The dialog built using DialGbox is "Mode dialog", only the other window of the program can be operated after the dialog is closed. Correspondingly, there is a "Non-Mode Dialog" and after the dialog is established, the user does not force the user to react immediately, but to the other window simultaneously accept user operations.
Second, establish a non-mode dialog box to use createDialg. You can establish the main window in WinMain, and the dialog handle is saved.
HDLGModeless = CREATEDIALOG
Hinstance,
TEXT ("Colorscrdlg"), // dialog template
HWnd,
Colorscrdlg // dialog message processing function
);
Third, the message loop adds processing for non-mode dialogs
"Non-Mode Dialog" is different from "Mode dialog", and the mode dialog is working, there is a message pump mechanism within it.
The Non-Mode dialog is like a normal window, and the message loop drive written by WinMain.
However, since it is a dialog, it has special processing for some messages, such as the "Tab" key, "entry" key, "enter" key, "" key, etc. used in each sub-control in the dialog.
Therefore, in the message loop, you need to provide a chance to intercept messages to the dialog box.
While (GetMessage (& MSG, NULL, 0, 0))
{
IF (HDLGModeless == 0 ||! IsdialogMessage (HDLGModeless, & MSG))
{
TranslateMessage (& MSG);
DispatchMessage (& MSG);
}
}
If the currently acquired message is the dialog message, isDialgMessage handles it to the dialog message processing function and returns TRUE.
No need to distribute.
Fourth, the destruction of the non-mode dialog box:
DestroyWindow (HDLG); When the user closes the dialog, the dialog message handler will receive a WM_CLOSE message, then call DESTROYWINDOW to destroy the Non-Mode dialog.
