- 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)
- Use bounding box intersections to determine which element is
hit.
- Transform mouse coordinates to local coordinates.
- Try to get osgText bounding box correct (or at least better)
- Refactor and unify common functionality of canvas::Window and
canvas::Image
- Make canvas::Image actually work
- Allow using canvases inside canvas::Image
* Use new canvas:// "protocol" to allow using canvases in
place of images
- Prepare for categorizing canvases:
* Move canvases to /canvas/by-index
* Later support linking to other nodes in subbranches of
/canvas
This code is non-functional, but contains most of the stubs to show what's required to add property get/set access, convert to from ghost & C++ types, and manage ownership. Element derived classes & inheritance (e.g., methods on image/path/map elements) will follow, along with some actual functionality!
- Refactor CanvasMgr into PropertyBasedMgr to be also used
for the Canvas GUI system.
- Get rid of tied properties in the Canvas system.
- Add new placement type 'window' for placing canvases onto
windows
- Pass mouse events to Window class (only if cursor is over
window)
- Refactor canvas placement clean up
- Allow hiding objects
- Use UTF-8 encoding for text elements
- Add paramter max-width to text elements
- Support stroke-linecap for path elements
- Fix mouse coords
- Set better mipmap filter
- The new map element automatically transforms geo coordinates
(lat, lon) to the according screen coordinates.
- Currently one type of projection is supported
(Sanson-Flamsteed projection)
- Add an update callback to calculate a bounding box for every
path to ensure correct culling of paths.
- Ensure OpenVG get's initialized even if elements are subject to
culling.
- Fix stupid memory corruption bug
- Fix bounding box calculations
- Fix docs
- Fix text size
- Expose setting background color
- Expose trigger for updating elements
- Untie nodes if deleting according element
- Allow deleting canvas, text and group elements
- Allow creating groups as children of groups
