Bug ID: 417811
Summary: click+hold on scrollbar thumb triggers scrolling to
that point on the track instead of allowing drag
Product: kate
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: application
Assignee: kwrite-bugs-n...@kde.org
Reporter: fantasai.b...@inkedblade.net
Target Milestone: ---
SUMMARY
One common method of interacting with a scrollbar is to drag the thumb to the
desired position. This is currently broken in Kate because the click needed to
activate dragging behavior (triggered by click+hold of the mouse) changes the
scroll position. Point-and-click scrolling should be triggered on mouseup, not
mousedown, and not if there was a drag operation in between.
STEPS TO REPRODUCE
1. Open a multi-page document
2. Scroll partway down.
3. Click on the scrollbar and hold down the mouse, as if you're going to drag
the scrollbar thumb to scroll the document.
4. Pause and observe what happened...
OBSERVED RESULT
Notice that even before you drag the thumb, the page has scrolled to some
random other point, depending on where in the scrollbar thumb you happened to
click.
EXPECTED RESULT
Holding down the mouse key on the scrollbar thumb should have no effect on the
scroll position.
