Hello, I've a problem when I try to use DirectGUI dialogs inside p3d files.

I've this file main.py:

Code: Select all: import direct.directbase.DirectStart from direct.gui.DirectDialog import OkDialog OkDialog( text = "Hello" ) run()

If I run it using python main.py, I correctly obtain this:

Now, if I pack it with packp3d -o app.p3d and run it with panda3d app.p3d I obtain this:

So, I can't see the frame of the dialog. Am I missing something? Thanks!

I'm using Panda3D 1.7.2 on Maverick Meerkat 32.

Have you tried using "-r models" on the packp3d command-line?

It doesn't work even with "-r models".

The symptom suggests that the file models/gui/dialog_box_gui.bam didn't get packed into your p3d file. As rdb suggested, using -r models should ensure that the entire models tree gets packed into your p3d file, so if it still doesn't work with that parameter, something is very strange.

What are the contents of your p3d file as revealed by the command "multify -tvf my.p3d"?

This is what I do:

Code: Select all: $ cat main.py import direct.directbase.DirectStart from direct.gui.DirectDialog import OkDialog OkDialog( text = "Hello" ) run() $ packp3d -r models -o my.p3d :AppRunner: Total Panda3D disk space used: 154 MB :AppRunner: Configured max usage is: 2048 MB :Packager(warning): No such file: /home/flavio/Desktop/prova/p3d_info.xml Generating my.p3d $ multify -tvf my.p3d 2 subfiles: 303 29% Jun 07 19:03 main.pyo 368 Jun 07 19:03 p3d_info.xml Last modification Jun 07 19:03

Oh, right--of course, "-r models" doesn't actually copy the bam file into your p3d file; but it should ensure that it is properly downloaded and available to your p3d file when it executes. Hmm, let me try to reproduce this.

Thank you! I'll file a bug report.

A strange (to me) aspect is that the package you pointed out doesn't contain the file you cited (models/gui/dialog_box_gui.bam): I can't find that file.

Found the problem. I don't build the pandatool tree as part of the rtdist build, so the flt2egg tool never gets built. Some models in the models tree are .flt, so they didn't get included properly. I'll fix it by simply enabling pandatool as part of the rtdist build.

For now, I advise manually calling flt2egg on the models that you need and including them yourself.

Ok, thank you so much!

Hi, I am having the problem in the OP even with the 1.8 models package (which contains gui/dialog_box_gui.bam, though). I have packed the file in the OP with:

Code: Select all: $ packp3d -r models -o app.p3d

I don't receive errors in the console or in the logs, but I can't see the dialog box. Is my command correct? Am I missing anything? Thank you!

I've noticed that there is a different behavior if you try to reference models (from 'models' package) with or without the prefix 'models/' in a p3d or in a py file. If you consider the following code:

Code: Select all: import direct.directbase.DirectStart for a in [ 'models/gui/dialog_box_gui', 'gui/dialog_box_gui', 'models/misc/fade', 'misc/fade' ]: np = loader.loadModel( a, okMissing = True ) print 'referenced_by: %-25s path: %s' % ( a, np.node().getFullpath().toOsSpecific() if np else 'not found' ) run()

It produces:

Code: Select all: $ python main.py [...] referenced_by: models/gui/dialog_box_gui path: /Developer/Panda3D/models/gui/dialog_box_gui.egg referenced_by: gui/dialog_box_gui path: /Developer/Panda3D/models/gui/dialog_box_gui.egg referenced_by: models/misc/fade path: /Developer/Panda3D/models/misc/fade.egg referenced_by: misc/fade path: /Developer/Panda3D/models/misc/fade.egg [...] $ packp3d -r models -o app.p3d [...] $ panda3d app.p3d [...] referenced_by: models/gui/dialog_box_gui path: not found referenced_by: gui/dialog_box_gui path: /Users/flavio/Library/Caches/Panda3D/hosts/runtime.panda3d.org_0f5faf88846080ae/models/cmu_1.8/gui/dialog_box_gui.bam referenced_by: models/misc/fade path: not found referenced_by: misc/fade path: /Users/flavio/Library/Caches/Panda3D/hosts/runtime.panda3d.org_0f5faf88846080ae/models/cmu_1.8/misc/fade.bam

As you can see, files referenced without the prefix 'models/' are correctly loaded with the p3d or the py file, while the ones referenced with the prefix 'models/' work only with the py file.

Now, in Panda's code the prefix 'models/' is used somewhere e.g.

direct/src/gui/DirectGuiGlobals.py:

Code: Select all: defaultDialogGeom = loader.loadModel('models/gui/dialog_box_gui', okMissing = True)

direct/src/showbase/Transitions.py:

Code: Select all: FadeModelName = "models/misc/fade"

I don't know if the two things are related and if it may be the reason of the problem (maybe Panda's code may be expected to behave differently than a generic p3d file).

It looks like that was the problem: the following code works using Python's interpreter and Panda's runtime too.

Code: Select all: import direct.directbase.DirectStart from panda3d.core import Filename, VirtualFileSystem from direct.gui.DirectDialog import OkDialog if base.appRunner: modelsRoot = Filename.expandFrom( '$MODELS_ROOT' ) vfs.mount( modelsRoot + '/models.cmu_1.8.mf', modelsRoot + '/models', VirtualFileSystem.MFReadOnly) OkDialog( text = "Hello" ) run()

Is it the best way to use the 'models' package?

Well, you've got a workaround, but this does seem like a bug. Can you submit a bug report on the launchpad, please?

Thanks!
