that finishes on its own
The hover delay only finished while the mouse was moving: a pointer resting
on a control produces no events, so nothing redrew the canvas and the wait
never reached its end - the tooltip appeared on the next pixel of movement
instead. It asked for its frames with schedule_extra_frame(), which only
arranges a timer whose event an idle event is assumed to follow, and
on_idle renders nothing unless the canvas was already dirty when it ran.
The wait and the animations now both use request_extra_frame(), which ends
on_idle with evt.RequestMore() and so obliges wx to deliver the next idle;
it is what 3DBed's fade uses. Asking for frames as fast as they come is
safe now that which frame is drawn comes from the clock rather than from
the frame count - a redraw that arrives early draws the same frame again.
Nothing explains a control while the control is being used, so no tooltip
appears while a slider is being dragged, a value typed into one, a combo
open or a layer card dragged. The pointer sits on the very thing being
edited, so a tooltip there covered the model exactly while the user was
watching it change. The full wait comes back afterwards rather than the
short one: having just let go of a slider is not a reason to be shown a
picture of it.
AnimatedTexture::texture_id() loses its time-to-next-frame out-parameter,
which nothing asks for any more.
The panel is pinned to the right edge of the canvas, so a tooltip left to
follow the mouse covers the very control it explains. panel_tooltip()
places every tooltip in the gizmo to the left of the panel instead - or of
the texture picker, while a tooltip is coming from inside that popup - the
same placement the picker itself already uses.
A tooltip can now carry pictures under its text: stills, or GIFs that loop
while it is open. Several settings in this panel describe a shape rather
than a number, and a sentence about a shape is read twice and understood
once. Files live in resources/images/texture_displacement and are named by
a tooltip; one that is missing is skipped, so a tooltip without its art yet
is exactly the text tooltip it was before.
AnimatedTexture decodes a file once and uploads a GL texture per frame -
wxImage for stills, wxGIFDecoder for GIFs, whose frames are composited here
with the disposal method each one asks for. An animation restarts when its
tooltip opens and asks the canvas for a redraw timed to its next frame.
Tile and Rotation are wired up as the first two; scripts/
gen_texture_displacement_tips.py draws their relief from the same
arithmetic the feature uses. docs/HLSD/tooltip-illustrations.md covers the
rest.
