- close all dialogs on reinit, set up style again, and then reopen all
(non-nasal generated) dialogs again
showDialog() is careful not to create a new FGDialog() if a dialog with the
same name is already open (active). But at this point it is already too late:
newDialog(), which was called shortly before, has already overwritten the
dialog properties. This leads to animated garbage in the best case, and a
segfault in format_callback() in the worst case.
- GUI::newDialog(): Don't you overwrite properties of an active dialog!
- GUI::readDir(): You may do that, but delete the old dialog first!
(necessary for reloading the GUI)
- FGDialog::makeObject(): only set format_callback() with setRenderCallback()
if the property is "live". Otherwise, only call it once at construction
time. This isn't only a performance improvement. Without this the label
was growing until it hit the limit (256).
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.
this patch is to clear a problem that I sometimes
encounter : FG locks when hitting the cancel button
of a dialog. In fact, an interator is always invalid
when it was used to erase a member of a collection.
The braces are here to help my debugger, and I also
removed a warning about unused variable.
scripts) to create dialogs at runtime. Augment "dialog-close" to take
a name argument, allowing code other than PUI callbacks to close
dialogs.
The changes to the GUI directory to enable this are actually minor,
basically amounting to using SGPropertyNode_ptr reference counting
(the GUI subsystem no longer "controls" the dialog property trees, so
it can't delete them).
menubar. This one allows regular command bindings, with the
(temporary) condition that every menu item must have a unique text
label. The new menubar is disabled by default; to enable it,
configure --with-new-menubar.
