I've installed some applications via apt. Here they are in the LXDE menu (note the two IDEs and also the "Graphics" menu are present):
If I right-click on the Application Launch Bar and select "Application Launch Bar Settings" like so:
The settings dialog does not have any of the applications I've installed (note also, the "Graphics" category is empty - there is no +
icon next to it):
The problem isn't limited to the launch bar settings dialog, either. If I right-click a PNG image in the file browser and select "Open With...", that dialog is also missing the newly-installed applications (note again the absence of the +
icon next to the "Graphics" category):
So: Why are installed applications not appearing in these dialogs, even though they do appear in the main application menu? Note that they are present in the applications database directory:
Environment: A fresh install of the latest Raspbian and the PIXEL desktop environment (which is essentially just a reskinned LXDE).
Note for those who think this is a duplicate of this question: It isn't. That other question is asking how to add applications to the launch bar. I know how to do that. I am not asking how to do that. I am asking: Why is LXDE not showing all of the installed applications in various dialogs which are supposed to list all of the installed applications?
