OK, easy beginner's question: what's wrong with this picture (I mean,
window)? The following code brings up a window, but none of my controls
appear in it. (The first two are vertical scrollbars, the third is a
panel divider I wrote myself.) Am I missing something?
pr
-------------------
void MakeNewWindow(WindowPtr myWindow, StringPtr windowName);
main()
{
WindowRecord myWindow;
EventRecord myEvent;
InitGraf(&thePort);
InitFonts();
InitWindows();
MakeNewWindow((WindowPtr)&myWindow, (StringPtr)"\ptesting");
while(!WaitNextEvent(mDownMask, &myEvent, 0xFFFFFFFF, 0L));
}
void MakeNewWindow(WindowPtr myWindow, StringPtr windowName)
{
GetNewWindow(128, myWindow, -1L);
SetPort(myWindow);
GetNewControl(128, myWindow);
GetNewControl(129, myWindow);
GetNewControl(130, myWindow);
SetWTitle(myWindow, windowName);
BeginUpdate(myWindow);
EraseRect(&myWindow->portRect);
DrawGrowIcon(myWindow);
DrawControls(myWindow);
EndUpdate(myWindow);
ShowWindow(myWindow);
}

Even thought I'm not a C programmer I'll take a stab at it. In article <1991Jan30.030241.27264@ux1.cso.uiuc.edu> resnick@cogsci.uiuc.edu (Pete Resnick) writes: >void MakeNewWindow(WindowPtr myWindow, StringPtr windowName) >{ > GetNewWindow(128, myWindow, -1L); > SetPort(myWindow); --> ShowWindow(myWindow); > GetNewControl(128, myWindow); > GetNewControl(129, myWindow); > GetNewControl(130, myWindow); > SetWTitle(myWindow, windowName); --> BeginUpdate(myWindow); --> EraseRect(&myWindow->portRect); > DrawGrowIcon(myWindow); > DrawControls(myWindow); --> EndUpdate(myWindow); --> ShowWindow(myWindow); >} I'm assuming that your are calling every thing correctly and that you do get a valid window. I'm also assuming that the window is invisible and that your sample program does not have an update routine. You need to show your window as soon as possible because you don't service an update event. You also don't need the beginupdate/endupdate. Even if you did have an update routine those calls would cancel the update event. (because it assumes that you just did an update) You don't need to erase the window or the last showwindow either.
