/*WARN(martin): this is super important
|
||||||
|
When the app is put in the background, it seems that if there are buffers in flight, the drawables to
|
||||||
|
can be leaked. This causes the gpu to allocate more and more drawables, until the app crashes.
|
||||||
|
(note: the drawable objects themselves are released once the app comes back to the forefront, but the
|
||||||
|
memory allocated in the GPU is never freed...)
|
||||||
|
|
||||||
|
In background the gpu seems to create drawable if none is available instead of actually
|
||||||
|
blocking on nextDrawable. These drawable never get freed.
|
||||||
|
This is not a problem if our shader is fast enough, since a previous drawable becomes
|
||||||
|
available before we finish the frame. But we want to protect against it anyway
|
||||||
|
|
||||||
|
The normal blocking mechanism of nextDrawable seems useless, so we implement our own scheme by
|
||||||
|
counting the number of drawables available with a semaphore that gets decremented here and
|
||||||
|
incremented in the presentedHandler of the drawable.
|
||||||
|
Thus we ensure that we don't consume more drawables than we are able to draw.
|
||||||
|
|
||||||
|
//TODO: we _also_ should stop trying to render if we detect that the app is in the background
|
||||||
|
or occluded, but we can't count only on this because there is a potential race between the
|
||||||
|
notification of background mode and the rendering.
|
||||||
|
|
||||||
|
//TODO: We should set a reasonable timeout and skip the frame and log an error in case we are stalled

Shortlist
|
||||||
|
---------
|
||||||
|
[x] let pass flat args in ui_size_push() and ui_box_set_size()
|
||||||
|
[>>] separate style stacks
|
||||||
|
[>] margins? as part of size, or different styling stack?
|
||||||
|
[>] animation time stack
|
||||||
|
[ ] Let build code set target style directly, and animate from current to target
|
||||||
|
[ ] filter styles stack by tag
|
||||||
|
[ ] image backgrounds/gradients?
|
||||||
|
[ ] animating open/close widgets?
|
||||||
|
|
||||||
|
|
||||||
|
Canvas Drawing
|
||||||
|
--------------
|
||||||
|
[.] Correctly handle resizing / viewport
|
||||||
|
[x] associate surfaces with mp_windows
|
||||||
|
[x] window resize resizes surface. Surface always renders to whole mp_window
|
||||||
|
[x] Add ability to create sub-views, and create surfaces for these
|
||||||
|
- window comes with a main view, so we can get a surface for the whole window
|
||||||
|
[>] Clean native mp_window_data struct (don't need to cache a lot of stuff here)
|
||||||
|
|
||||||
|
[.] Add images bliting
|
||||||
|
[x] Clean, rename uv vs texUV stuff
|
||||||
|
[>] Destroy stuff
|
||||||
|
[>] More unified handle system
|
||||||
|
[.] Rounded images (sortof)
|
||||||
|
[ ] path clipped images
|
||||||
|
|
||||||
|
[ ] Add color gradients?
|
||||||
|
[ ] Make canvas implicit?
|
||||||
|
[/] Handle based error signaling
|
||||||
|
[/] Allow polling events in main thread, and updating/rendering in background thread.
|
||||||
|
|
||||||
|
[x] font metrics shouldn't depend on surface, & font
|
||||||
|
shouldn't really depend on canvas either???
|
||||||
|
> meaning we should be able to pass fonts without canvas in ui
|
||||||
|
> and only pass canvas when drawing at the end...
|
||||||
|
|
||||||
|
UI
|
||||||
|
--
|
||||||
|
[x] Make gui context implicit?
|
||||||
|
[x] Uniform ui_box struct + cache widgets
|
||||||
|
[x] Prune unused boxes
|
||||||
|
[.] Layout boxes
|
||||||
|
[x] basic two pass layout
|
||||||
|
[x] Layout from start or end
|
||||||
|
[>] Add overflow flags to layout, & solve conflicts
|
||||||
|
|
||||||
|
[x] Temporarily push transform and text flip when rendering UI, so that the coord system is y down, origin at top left
|
||||||
|
[x] Canvas render the same size on a high-dpi surface
|
||||||
|
> it works with abstract 'pixel' units, which are transformed to pixels in the shader, according to backing store scaling
|
||||||
|
|
||||||
|
[.] Style struct and style stack
|
||||||
|
[ ] Maybe use individual stack for different style attributes
|
||||||
|
[x] Pass initial style in ui_begin_frame()
|
||||||
|
|
||||||
|
[.] Draw boxes
|
||||||
|
[x] use flags to enable/disable drawing each feature
|
||||||
|
[ ] active/hovered transitions
|
||||||
|
|
||||||
|
[x] Change input state handling a move it to app layer
|
||||||
|
[x] Compute signals for ui_box
|
||||||
|
[x] Use ui_size_push() and pass axis instead of ui_width/height_push()
|
||||||
|
[>] Use value is ui_size as margin when kind == text or == children?
|
||||||
|
|
||||||
|
[ ] Allow animating sizes according to hot/active?
|
||||||
|
|
||||||
|
[ ] Basic helpers
|
||||||
|
[.] button
|
||||||
|
[.] slider (or rather, scroll bar)
|
||||||
|
[.] simple spacers
|
||||||
|
[ ] have a flag for non-cached stuff
|
||||||
|
[.] scrolling panel
|
||||||
|
[ ] Allow/disallow scrolling in x/y
|
||||||
|
[ ] Scroll with mousewheel
|
||||||
|
[/] add margins to scrollbars (disallow scrollbars crossing)
|
||||||
|
|
||||||
|
[?] Maybe let builder code handle "active"/"hot" state, since it
|
||||||
|
depends on the widgets
|
||||||
|
[ ] On the other hand, this state must be set before layouting, in
|
||||||
|
particular font/fontSize -> maybe do a pass for static layout,
|
||||||
|
instead of doing it in box creation...
|
||||||
|
[ ] this way we can compute styling after user has set active/hot, but before layout
|
||||||
|
> Maybe just let user set style selector, and provide persistent state bits that can
|
||||||
|
> be used in any way? (to replace eg active/hot?) or perhaps not needed if we have just
|
||||||
|
> 'dragging' state
|
||||||
|
|
||||||
|
|
||||||
|
[x] Mask mouse outside of parent rects -> maintain clip stack and clip mouse against it
|
||||||
|
[x] Mask mouse below panels/other widgets
|
||||||
|
[x] popups and tooltips
|
||||||
|
[x] allow pushing/popping boxes irrespective of parent/child relation
|
||||||
|
[x] ui_begin_frame() prepares two containers, user ui goes in the first one
|
||||||
|
[x] tooltips and menus go to the second one
|
||||||
|
[x] Add menus
|
||||||
|
[ ] line editing widget
|
||||||
|
|
||||||
|
Misc
|
||||||
|
----
|
||||||
|
[x] Split metal surface and metal painter (but put them in the same compilation unit?)
|
||||||
|
[x] Have only one rect struct
|
||||||
|
[x] Shorten mp_string to str8
|
||||||
|
|
||||||
|
[ ] Better/Simpler time API
|
||||||
|
|
||||||
|
[/] Frame throttling
|
||||||
|
[x] For now, we always wait on vblank during mg_surface_present(), regardless of target fps
|
||||||
|
[ ] Then actually get the correct display interval from the surface's current monitor
|
||||||
|
[ ] Allow waiting for more display interval than one? (ie allow throttling at 30fps for a 60fps display)
|
||||||
|
|
||||||
|
[/] split osx_app and move all platform independant stuff outside
|
||||||
|
|
||||||
|
[ ] Sort out mg_matrix_push/pop() -> transform vs. set...
|
