Correct linux menu launch shortcut

[Pickle]

The linux gtk menu launcher was incorrectly set to exec bibledit-gtk it should be bibledit-desktop.

The icon entry also did not refer to an actual icon, this commit change it to the xpm icon. The commit also changes references to bibledit-gtk. Readme and changelog reference were not changed.

This touches some stuff we mod in the gtk3 branch. But if it helps you here, I'll deal with those potential conflicts later.

@Pickle for tidiness of git log --oneline, please put a single-line description of your commit, and then a blank and then after that you can put any number of lines of arbitrary length for further description. Thanks for this PR.

Does this merge at least temporarily fix this issue for linux: #111?

[Pickle]

@postiffm i will make future commits like you ask

@LAfricain im not sure it is exactly the same problem. What I did was run sudo make install. I saw i had the menu entry so it at least copied the desktop file. But i found it would not launch the application and it did not have any icon.

I thought we already fixed this by pulling some gtk3 branch commits into the master branch. But I haven't independently verified if that is correct.

I checkout the gtk3 branch last night and im not sure my icon changes are correct. GTK3 has the same icon problem and did not work adding the xpm extension. I looked at another application and its desktop file referenced a icon with no extension, so the original icon setting could be correct. What i think is missing is the make install is not copying a png to the pix folder. I will test this out tonight and if it works I think I just need to find where in the makefile to copy a png to the right folder.

Excellent, I saw the commit and this is exactly the port of the changes I made in the gtk3 branch to master. Yes, it should fix the problem @LAfricain mentioned in #111 for Linux with GTK2 (but not for Windows).

What problem are you talking about? Are you sure you have the latest version of gtk3 branch? I think I verified that all *.png files are copied to the correct destinations. What may be missing is the launch of update-desktop-database command line utility. I don't recommend adding it explicitly because AFAIK this should be a job of the distribution packages.

@rluzynski master checked out. ran make uninstall checked out gtk3 branch and built make install went to the menu and i have a working menu entry that launches proper but has no icon.

I have beyond compare installed and i was curious how their desktop file looked and i found it was using just bcomp with no extension. So then i wondered where they put their icon image. I found one in the /usr/share/pix folder (need to confirm full path), but there was not one for bible edit in this location. So my test will be to copy a bible edit png to the location and see if I get the icon showing up. Maybe the location is specific to the distro? Im currently running linux mint with xfce.

ok i ran the test, on the gtk3 branch i need to copy bibledit-desktop.xpm to /usr/share/pixmaps. No changes are needed to the desktop file. But once the file is there the image shows up in my menu.

[Pickle]

I pretty sure I have it figured out. master gtk2: The extension is not needed and the xpm is installed in pixmaps branch gtk3: xpm is NOT installed in pixmaps

Comparing how both projects are setup in the makefiles, bibledit-desktop/pix/Makefile.am in gtk2 has:

appicondir = $(datadir)/pixmaps
appicon_DATA = bibledit-desktop.xpm

adding the lines back into gtk3 makefile now copies the xpm to pixmaps and the icon is rendered in menu.

I can make PR's if no one disagrees with this assessment.

Sounds good. Thanks @Pickle
