Floating palette classes
|
|
|
|
|
|
|
|
|
|
|
|
Implements tearable tool palletes
|
|
|
|
|
|
|
|
|
|
|
|
### Standard usage:
|
|
|
|
|
|
|
|
|
|
|
|
Include UTearOffPalette.r in your project for floating window templates
|
|
|
|
|
|
|
|
|
|
|
|
Initialization
|
|
|
|
|
|
call InitUTearOffPalette(your-application) on startup
|
|
|
|
|
|
|
|
|
|
|
|
To create an instance of a palette:
|
|
|
|
|
|
Create a stand-alone PPob that contains the palette as it appears in the floating
|
|
|
|
|
|
window and one as it appears imbedded in place. These may be the same PPob If you
|
|
|
|
|
|
want special shading in the palette, do it in its topmost view
|
|
|
|
|
|
|
|
|
|
|
|
In the window containing the palette:
|
|
|
|
|
|
a) create CTearOffBar, empty view and of the same size as stand-alone palette.
|
|
|
|
|
|
CTearOffBar contains ID of the stand-alone and imbedded palettes
|
|
|
|
|
|
b) in window::FinishCreateSelf, add window as AddListener to CTearOffBar
|
|
|
|
|
|
|
|
|
|
|
|
c) inside window, handle the palette messages:
|
|
|
|
|
|
virtual void ListenToMessage(MessageT inMessage, void *ioParam)
|
|
|
|
|
|
{
|
|
|
|
|
|
switch (inMessage)
|
|
|
|
|
|
{
|
|
|
|
|
|
case msg_SetTearOffPalette:
|
|
|
|
|
|
// Link in the palette controls
|
|
|
|
|
|
LView * newView = (LView*)ioParam;
|
|
|
|
|
|
if (newView->GetPaneID() == p1_ID)
|
|
|
|
|
|
fP1 = newView;
|
|
|
|
|
|
RefreshControls();
|
|
|
|
|
|
break;
|
|
|
|
|
|
|
|
|
|
|
|
case msg_RemoveTearOffPalette:
|
|
|
|
|
|
// Unlink the palette controls
|
|
|
|
|
|
PaneIDT paneID = (PaneIDT)ioParam;
|
|
|
|
|
|
if (paneID == p1_ID)
|
|
|
|
|
|
fP1 = NULL;
|
|
|
|
|
|
break;
|
|
|
|
|
|
}
|
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
|
|
d) since your window will not always have controls linked up,
|
|
|
|
|
|
make sure that you can deal with your control panes being NULL.
|
|
|
|
|
|
|
|
|
|
|
|
e) If you want to reposition views in response to palette being torn off,
|
|
|
|
|
|
subclass CTearOffBar and override ShowPalette and HidePalette methods.
|
|
|
|
|
|
You can also check set the fAutoResize flag in CTearOffBar, and view will
|
|
|
|
|
|
shrink to 0,0 when palette is torn out.
|
|
|
|
|
|
|
|
|
|
|
|
f) When frontmost, your window will get broadcasted messages from
|
|
|
|
|
|
broadcasters in the palette
|
|
|
|
|
|
|
|
|
|
|
|
g) The manager can be used as public message relay. It is both an
|
|
|
|
|
|
LListener and an LBroadcaster. It generates no messages of it's
|
|
|
|
|
|
own, but passes on every message that it receives.
|
|
|
|
|
|
|
|
|
|
|
|
### Design notes:
|
|
|
|
|
|
CTearOffBar (FBar) and TearOffWindow (FWindow)
|
|
|
|
|
|
do not know anything about each other, communications happens through
|
|
|
|
|
|
CTearOffManager (FManager).
|
|
|
|
|
|
|
|
|
|
|
|
FBar and its listener (usually the container window), register with FManager.
|
|
|
|
|
|
FBar & FWindow broadcast all their messages through the manager,
|
|
|
|
|
|
and manager dispatches them.
|
|
|
|
|
|
|
|
|
|
|
|
Since FWindow is always created from a single PPob template, we do not put
|
|
|
|
|
|
any palette customization flags in the window custom template. All flags
|
|
|
|
|
|
are in the palette PPob. This causes some things to be initialized in
|
|
|
|
|
|
weird ways (fVisibility, fTransparentPane).
|
|
|
|
|
|
|
|
|
|
|
|
More to come...
