| I tried to create a new window for the text editor, but it didn't work...

Q: | When I tried to create my own window to be used as a parent window for the text editor (instead of the DeskTop window), and when I passed the address of my window to TE_open, the editor went blank (it did not display the file contents on the screen, although the editing seemed to work). What is wrong?
A: | I was also very surprised when I noticed this. After some investigations, I concluded that the window passed to TE_open must not be "dirty" (i.e. it must not have WF_DIRTY flag set), but windows created by WinOpen are "dirty" by default. So, you need to clear "dirty" flag manually before calling TE_open. This is straightforward. For example,
    WIN_RECT myRect = {0, 16, 159, 92};
    WINDOW myWin;
    TEXT_EDIT te;
    ...
    WinOpen (&myWin, &myRect, WF_NOBORDER);
    myWin.Flags &= ~WF_DIRTY;
    TE_open (&te, &myWin, &myRect, ...);
Anyway, there is no strong reasons to use any windows other than DeskTop as a parent window, except if you want to use the whole screen for the editing area (the desktop window is clipped in the toolbar area). But, note that using whole screen for editing is not so good idea. The editor expects that the menu is on the top. So, if you press F1 etc. while doing "full-screen" editing, your screen will be trashed, because the editor will open the menu, and it will expect that the toolbar is at the top, etc. etc. Try to see. The solution? Disable all keys like F1, etc. in the event handler (e.g. do not pass them to TE_handleEvent) if you really want to do full screen editing...
