TabbedPane improvements

Hiding cropped line is now implemented in master branch.

Hiding cropped edge, TY so much!. Would still like to be able to replace or hide the scroller and have the above described scrolling.

[DevCharly]

Thanks for your feedback. What exactly is the problem? Is it just the cropped line? I don't like that as well. Can't remember the reason for not removing it yet. But will do in next release.

Want also change the arrow colors slightly so that it is easier to see the difference between enabled and disabled arrows.

Any other issues? Is something wrong with the general functionality of TabScroller? Thx.

Yes that cropped line has been an eyesore for years. Im ok with the buttons but they dont respond as a normal scrollbar would. It would be nice to be able to literally scroll right to left like you can do in the IJ tab run. My ideal option would be to be able to replace the buttons with an "overflow" menu like IJ so that hidden tabs can be selected. and to have the tabs scroll using normal scrolling (from trackpad gestures or arrow keys)

I realize thats asking alot, but to get this tab layout into this century that CroppedEdge line simply must go.

There could be some settings to:

• Have the left scroller on the left of the tabs, and the right scroller on the right of the tabs.
• The mouse wheel over the tabs could scroll left right.

Note that while I would love having the above to improve the look, I would be afraid that it breaks my hack of the BasicTabbedPaneUI which allows me to have a component on the left and/or a component on the right. See:

By-the-way, if I had a simple way to add my left and right components without a hack in FlatLaf, that would be great 😉

[DevCharly]

Thanks for your great ideas.

To summarize:

• remove cropped line
• arrow buttons should repeat scrolling as long as pressed (implemented in #187)
• scroll with mouse wheel or trackpad if mouse is over tabs area; if active tab becomes invisible (scrolled to outside), then it should be scrolled back to visible when mouse leaves tabs area (as in IJ) (implemented in #187)
• "overflow" menu like IJ (implemented in #190)
• left arrow button on left side of tabs area and show left/right buttons only if necessary (hide disabled arrows) (implemented in #211)
• support adding custom components to left and right sides of tabs area (implemented in #192)
• optionally shorten long tab text (implemented in #199)
• close button in tabs (issue #31) (implemented in #193)

With all that improvements it would also make sense to change the default tab layout policy to scrolling to avoid multi-line tabs.

I am not sure this bug should be closed: the possible improvements mentioned in @DevCharly 's 2nd comment are not implemented and they perfectly match the idea of this bug entry.

[DevCharly]

Yep, still like to implement improvements for tabbed panes...
