You would think that the process involved in changing the height and position of the KDE panel should not need documentation, but apparently, it does. Partly because it is not as obvious as it should be.
It is not the type of subject I write tutorials about, but one too many search traffic to this website on the topic moved me to write this very short tutorial. The process is not even complicated or hard to figure out, if you know what to do.
To change the properties of the panel, which by default is on the bottom edge of the desktop, you need to access the Panel Tool Box widget located on the extreme right edge of the panel. Depending on the distribution you are using, the panel could be locked or unlocked.
If it is locked, the Panel Tool Box widget will be hidden. To make it visible, unlock the widgets – right-click on the panel and select Unlock Widgets.
Then, click on the Panel Tool Box widget.
This is a screen shot of a section of Panel Tool Box. To change the height of the panel, place the cursor over the Height button, left-click and hold and drag up or down. Up if you want to increase the height, and down, it you want to decrease it. To move the panel to the top edge of the desktop, repeat the operation, but this time, place the cursor over Screen Edge button. You can also move the panel to the right or left edge of the desktop.
