Panel size fluctuated due to change in task buttons about lxqt-panel HOT 8 CLOSED

Don't worry about it. I know how to fix it. We discussed it with Kuzma
some time ago. I just forgot to do it. I'll fix it tomorrow.

I noted some UI glitches about panel sizing.
Currently the height of the panel seems to be determined by its content.
When I open a new window, a new task button is created in the panel.
Then, the icon and text of the task button may have more height than the
panel itself, this causes automatic resize of the panel and the height of
the panel grows.
When I close the window, the task button is removed from the panel.
The max height of the remaing plugins is smaller. So the panel is again
resized with its height shrinked, causing fluctuation of panel height and
visual disturbance.

How to reproduce:

1. close all windows, add mainmenu, desktopswitch, pulseaudio, and
   calendar to the panel.
2. Use fusion-qt4 style.
3. open a new window, the height of panel may grow sometimes
4. close the window again, then the height of the panel shrinks.

Maybe we should set the height of the panel manually?

Just tested the latest code in git but it still has the problem.
When the first taskbar button is created, the panel height grows.

How are you tested? Is you installed plugins before? I changed the taskbar plugin code, if you don't installed it, old version of the plugin used.

I delete all of the old libs and reinstalled the lastes code. The problem is only partially fixed.
That means, it cannot be reproduced most of the time, but it's application-specific.
For example, if I launch Roxterm or Firefox, the panel height will increase when the window shows up.
When I launch pcmanfm-qt, lxqt-about, or some other tools, it panel height does not change at all.

OK, it's caused by different sizes of window icons.
When I turn off icons of the task bar and show window titles only, the bug cannot be reproduced anymore.
So I think it's a problem related to window icon.

After a significant amount of hours of testing and hacking, I say that the problem is not the size of icons. @PCMan, when I open pcmanfm-qt the panel height doesn't change here either, but if I open a folder in pcmanfm-qt, the panel height changes!! Doesn't it happen with you too? Like you said in the begging, "the height of the panel seems to be determined by its content". Specifically, the taskbar's content. Why doesn't lxqt's panel have the config option to set its height, like KDE, Xfce, Gnome2...?

If you set a maximum height to the taskbar buttons, the problem seems to be fixed. But we don't want to set a maximum height for them, right? If the panel had a maximum height, the problem would be solved. I could make a PR for that.
