canvas::Window now optionally creates a second canvas for showing
window decoration. After setting its dimensions with the property
"decoration-border" a Nasal based window decorator should add the
required elements to the decoration canvas.
Using the properties "shadow-radius" and "shadow-inset" a drop
shadow can be added to the window.
- Add option 'capture-events' to canvas aircraft and scenery
placements to allow events being forwarded to the respective
canvas.
- Clean up and restructure parts of the mouse event/picking
handling to support forwarding events to canvasses.
Ensure canvas displayed inside GUI windows are updated in the same
frame as the according window is made visible. This prevents
showing previous contents for the first frame.
- Don't capture mouse events if mouse mode has
pass-through disabled. This behaviour is
consistent with the PUI dialogs and allows
changing moving view and controls while above
any GUI dialog.
- Add option to canvas windows to ignore all
events and let them pass through
("capture-events").
- Setting 'resize' property to true on canvas::Window shows
resize icons and exposes requested size to the property
tree. This can be used eg. from Nasal to actually resize
the window and/or show a preview of the resized window
while resizing.
- Event handling now ignores events which have already
been handled. Before eg. clicking inside a window
also caused picking to be performed inside the
scene which is for sure not the expected behaviour.
- Also forwards scroll wheel events from canvas::Window.
If the size of a Canvas changes also the texture id
changes. We now retrieve the texture id for the CanvasWidget
every frame to ensure it uses the latest texture instance.
- Redraw all canvases in the frame OpenVG is initialized.
Otherwise if multiple canvases are created in the same frame
only one of them would get correctly updated.
If OpenVG/ShivaVG is initialized nothing is drawn in the same
frame, therefore we need to draw another frame to ensure all
paths are rendered correctly.
- Only render the canvas if something has actually changed
(Currently checked by looking for modified properties).
- Only write bounding box to property tree if it has been
recalculated (until now this happened every frame).
Currently if a SGPropertyNode is removed from the property tree
only for this single node a childRemoved event is triggered. So
if we just check for a specific child to be removed, we will never
be notified. This commit manually triggers the event recursively
for all children but this should probably go directly into simgear.
- Groups store property nodes for different styles and pass them
to child elements on creation (No dynamic updates yet)
- Use StyleSetter map instead of loads of if/else if statements
for setting element styles.
- Unify element style properties (Only use one property, instead
of multiple like it has been with colors)
- Fix: Create only one element per property node (Was two)
