Improve how ruler labels are shown
I tested this. I think it is good. I do not love how the time can be printed beyond the ruler. But this is probably better than cutting it of when it can be shown.
Why? I am not keen to make personal little changes that might introduce some side effects or problem.
I think this one is an obvious visual improvement that can benefit most users, not just me personally without apparent side effects.
Technically though, Repeater's model property holds the number of repeated objects, and
parent.width / (intervalSeconds * profile.fps * timeScale)
gets rounded up half way, and rounded down otherwise.
Math.ceil ensures that at least one objects is shown even if the ruler's width (parent.width) is really small.
If the ruler's width is the same as the interval, two objects are shown, and so forth.
label.width is taking the hint from width in (x + width), which looks like it's intended to be there to hide a object only if the right side of the entire object reaches the tracksFlickable.contentX.
I do not love how the time can be printed beyond the ruler.
I can make the label to show only if it is within the ruler by adding:
&& (x + width + label.width) < rulerTop.width
to
44: visible: ((x + width + label.width) > tracksFlickable.contentX) && (x < tracksFlickable.contentX + tracksFlickable.width) // left edge
in Ruler.qml.
As for "why?" please do not assume I have read the forum, and feel free to link to an explanation: https://forum.shotcut.org/t/improve-timeline-keyframe-ruler-label-display/36251
This is a very minor finesse thing that I am not interested in to change in the near term as there are currently two development paths: stability (with fixes) and major changes. But I am leaving it open to consider for future.
