The dialog handling has been written at a time when only one dialog was
shown at the same time, and dialogs were shallow -- with only children, but
no grand-children. This makes finding a draggable spot on modern, dialogs
with nested objects quite a challenge. The patches fixes this, and other things:
- check full object tree on button press, not only the outmost layer;
and don't give up just because we are in *something* (which could well be
something harmless, like a group); only ignore a few, sensible objects
(we don't want to drag after a click on a button or into an input field)
- don't lose dialogs as easily when dragging too fast (it does still happen
if one manages to enter an editable field while dragging, but this is
a plib problem and I don't feel like fixing that now :-)
- don't "live"-update input fields while they are in edit mode
- remove some "if (foo) delete foo;" redundancy
little larger.
The text widget can now be meaningfully associated with a property; in
PUI, it's "value" isn't the same thing as its label, but we can hack
things to treat them symmetrically.
Commit an experimental "live" property that can be set on widgets to
cause them to update their values every frame. This works great for
text widgets, as above. Note that this synchronization is input-only:
no support is provided (or needed -- the GUI only changes when the
user does something) for writing those properties out every frame.
for a while, it turned out to be pretty easy to implement. Also, the
property picker is now non-modal, I presume the modality wasn't an
intentional feature.
scene management code and organizing it within simgear. My strategy is
to identify the code I want to move, and break it's direct flightgear
dependencies. Then it will be free to move over into the simgear package.
- Moved some property specific code into simgear/props/
- Split out the condition code from fgfs/src/Main/fg_props and put it
in it's own source file in simgear/props/
- Created a scene subdirectory for scenery, model, and material property
related code.
- Moved location.[ch]xx into simgear/scene/model/
- The location and condition code had dependencies on flightgear's global
state (all the globals-> stuff, the flightgear property tree, etc.) SimGear
code can't depend on it so that data has to be passed as parameters to the
functions/methods/constructors.
- This need to pass data as function parameters had a dramatic cascading
effect throughout the FlightGear code.
Fix memory leaks (PUI doesn't make copies of lists, so we have to make
our own copies and keep pointers to them).
Adjust for new method names in NewGUI.
Move the GUIInfo struct into the cxx file so that it's not part of the
public interface.
