I'm having some problems with the CScrollWindow class. I'm not
getting any response to clicks on the scrollbars. I've stepped
through CView::DispatchClick, and it looks like I'm just not getting
the scroll bars back from CView::FindSubview. I've looked at what's
done in the Art example, and the CClipboard, but it looks like I'm
doing basically the same thing. I'm obviously getting something
wrong, but I just don't see it.
The routine gets called from my document class like so:
w->IClassWindow(30774, FALSE, gDesktop, this, aClass);
[BClassWindow is a subclass of CWindow. scrollPane is CScrollPane.
classPicture is BClassWindow, which is a subclass of CPanorama with
only the Draw() method overridden.]
void BClassWindow::IClassWindow(
short WINDid,
Boolean aFloating,
CDesktop *anEnclosure,
CDirector *aSupervisor,
BClass *theCls
) {
Str255 title;
Rect bounds;
Point y;
inherited::IWindow(WINDid, aFloating, anEnclosure, aSupervisor);
this->theClass = theCls;
theCls->ClassName((char *) title);
CtoPstr(title);
this->SetTitle(title);
this->SetActClick(true);
/*
* setup scroll pane
*/
scrollPane = new(CScrollPane);
scrollPane->IScrollPane(this, this, 0, 0, 0, 0, sizELASTIC,
sizELASTIC, true, true, true);
scrollPane->FitToEnclFrame(true, true);
scrollPane->DoClick(y, 0, 0);
/*
* setup panorama
*/
classPicture = new(BClassPanorama);
classPicture->IPanorama(scrollPane, this, 0, 0, 0, 0,
sizELASTIC, sizELASTIC);
classPicture->FitToEnclFrame(true, true);
/*
* install the panorama into the scroll frame
*/
scrollPane->InstallPanorama(classPicture);
/*
* grow the panorama
*/
SetRect(&bounds, 0, 0, 500, 500);
classPicture->SetBounds(&bounds);
classPicture->SetScales(1, 1);
/*
* Put the window onto the screen
*/
this->Select();
};

This seems very confusing. I'm not sure what you're trying to do in your initialization class. Most of it looks like it belongs in your document's initialization method. It looks like your trying to have CScrollWindow act as a window and a director. For instance, you init the scrollPane variable with "this" for both its supervisor and its enclosure. I'm pretty sure that CWindow assumes that its supervisor is a decendent of CDirector, which may cause your implementation to crash eventually. I must admit tha I haven't quite figured out why your clicks haven't been dispatched properly, but I though that what I've just said might give you a clue. Good Luck.

My problem with not getting clicks seems to be that I was calling FitToEnclFrame() rather than FitToEnclosure(). The pane just wasn't where I thought it was. Switching the two calls solved the problem. -- James Moore | Nil aon .sig maith agam anois - Santa Cruz Operation UNIX Tech Support | B'fheidir an tseachtaine seo jamesm@sco.com | chugainn.
