not everything is display correctly

[Marcin Niechcial]

Binary package hint: tuxguitar

in polish
podczas uruchamiania programu splashscreen nie jest wyswietlany w całości, a następnie sciezki instrumentów również się nie wyświetlają, oprócz kilku taktów pierwszego instrumentu, nie wiem co jest za to odpowiedzialne ale w poprzedniej wersji w jaunty 9.04 problem nie występował

I do not know how to describe it in English but will try to help translate.google.com

when I start tuxguitar splashscreen isnot displayed in its entirety, then the path of instruments do not show all tracks, except for a few bars of the first instrument, I do not know what is responsible for it but the previous version of the jaunty 9.04 issue does not occur

now i'm using karmic after dist-upgrade from jaunty, i'm tryin reinstall but with no effect

I'm experiencing the same problem since the time I upgraded my Ubuntu to Karmic beta.

[Julian (julian-casadesus)]

It happens with SWT and GTK versions higher than 2.17.
SWT team fixed this problem on 3.6 develpment version.

You can try download swt 3.6M2 for linux-gtk-[your_arch]
from http://www.eclipse.org/swt/
uncompress the downloaded file and exec on a terminal:

export CLASSPATH=/Folder_Where_Is_SWT/swt.jar
tuxguitar

The problem with the splash screen may still be there, but the other issues will be solved.

[MasterProg (masterprog)]

Thanks, it works as expected now (including splash screen).

@Julian,

Do you have pointer to the upstream svn revision that fixed this bug? I will try to backport the change to karmic version of swt-gtk.

[Julian (julian-casadesus)]

@Onkar,
No i don't have idea at what SVN revision was it fixed.
I can only tell you that the bug is fixed at GC class:

org.eclipse.swt.graphics.GC.java, At "initCairo()" method
where cleary, there is an IF condition checking if GTK version is lesser than 2, 17, 0
I have tested override this methood content to 3.5 version of SWT, and the problem was gone.

However after write this post, i saw that there are other problems than graphics, ( also fixed on 3.6 )
but not sure where are they fixed.

These other problems, are also reproducible in eclipse (not only in tuxguitar).
some buttons just don't works with mouse clicks. ( yes with keyboard )

In tuxguitar you can reproduce the problem:
* Menu: Tools -> Plugins
* Select any plugin, and click "Info" button.
It only gain focus, but listeners are not fired, but if you press SPACE or ENTER listeners work.

In eclipse ( may depend the version, i don't have it from repositories )
* Just open a source file, and press "Ctrl + F"
* Type a search text, and click "Find" button..

I found problems on some other eclipse buttons too. but it's hard to give you steps to reproduce them.

I had planned to release tuxguitar 1.2 this weekend but now i don't have idea what to do with this problem..
It seems that SWT versions lesser than 3.6, just can't coexist with new GTK versions.

@MasterProg,
The splash screen sometimes works.... but sometimes don't, even in 3.6
i don't know exactly the reason, but i was able to fix it from tuxguitar code calling an update inmediatly after the windows opens.
and this fix yes works for lesser SWT versions of GTK.

[Onkar Shinde (onkarshinde)]

Subscribing Adrian. He is more familiar with swt-gtk than me.

[Dave Roberts (drob-blueyonder)]

I removed Tuxguitar 1.1 and installed Tuxguitar 1.2 from the Tuxguitar website.
All the above issues appear to be fine in 1.2, display, buttons etc.
I had all of the above problems with V1.1.
The only slight issue I had with 1.2 was with my netbook, the staff lines were not displaying ,I fixed from a thread on the Tuxguitar forums.
Tuxguitar 1.2 installed fine on my desktop.
I only use the program as a playback tool,but so far 1.2 is a solution for me.

[Julian (julian-casadesus)]

Dave, 1.2 deb package from official website, includes swt 3.6M3 library (just because this issue) as default
but i don't think that the future repository version will include it, because swt package already exists in repositories.
So in other words, this problem will not be solved until a swt package upgrade.

[Dave Roberts (drob-blueyonder)]

Julian don't know wether this is relavent but I did a search in Synaptic post install of TG1.2 for "swt"and the package listed as installed is libswt-gtk.3.4*.

Does the TG1.2 package I installed contain within it the 3.6M3 library and is this the library TG1.2 is using?

[Julian (julian-casadesus)]

Yes, it contains 3.6M3 inside.
To don't make conflicts with repository version of SWT, this .deb package have SWT library in a different place.

The file included in the package is at: "/usr/share/java/tuxguitar/swt.jar"
while repository version, is at "/usr/share/java/swt.jar"

You can check what swt.jar is used by running: tuxguitar -i

or you could uninstall libswt-* packages, and tuxguitar will still works.

for me I did this :
and now notes heads are displayed correctly

http://tuxguitar.herac.com.ar/forum/5/1331/no-lines-for-notes-and-tabs/

"
Morii, this topic sames to be related to same problem that this one: http://www.tuxguitar.com.ar/forum/5/1437/1-2-fingerboard-no-strings/

Lets post new comments in this one.

I'll say same as my last post in the other topic.

Try to open with any text editor the file:
~/.tuxguitar-1.2/config.properties

(if somebody don't knows.. ~/ means the user's home folder.. e.g: /home/[username]/ )

* It's important to edit this file when tuxguitar is closed.

And try append this line:
painter.force-os-defaults=true

Save the file, and run the application..
so does it fix something ?"

[anarsoul (anarsoul)]

I've created PPA with updated version of libswt (it's cause of a problem), just upgrade libswt from my ppa and problem should gone away.

sudo apt-add-repository ppa:anarsoul/anarsoul
sudo apt-get update
sudo apt-get upgrade

[Micah Gersten (micahg)]

Marking this triaged since the issue is known, although, I don't think we can "fix" this until swt-gtk 3.6 is packaged.

[anarsoul (anarsoul)]

Actually, problem is fixed in swt-gtk-3.5.2, so if it's possible to bump version in releases with swt-gtk-3.5.x it's better to do this. No need in swt-gtk-3.6 for these releases.
