building python program with a gui identical with pyqt andpygtk-SOLVED

gnu_D · 2010-01-22 08:36:28

Hi,

I want to make my Python program to find which DE is in and use that gui toolkit i.e pygtk on GNOME, pyqt on KDE, but my problem is the theme icons, I need to get the current theme icon from kde when using pyqt, in the specification here: http://www.riverbankcomputing.co.uk/sta … qicon.html says there is a function named fromTheme in the QIcon widget, but when I use it in python says: 'QIcon' object has no attribute 'fromTheme, this is my test code:

icon = QtGui.QIcon().fromTheme("edit-undo")

and this is the full error:

Traceback (most recent call last):
  File "qt_guilogin.py", line 135, in <module>
    qtGui()
  File "qt_guilogin.py", line 22, in __init__
    self.loginWindow()
  File "qt_guilogin.py", line 52, in loginWindow
    QtGui.QIcon().fromTheme("edit-undo")
AttributeError: 'QIcon' object has no attribute 'fromTheme

This is the pygtk version of the full code:

        hbUPart = gtk.HBox()
        usrImg = gtk.Image()
        icon_theme = gtk.icon_theme_get_default() # Current theme instance        
        try:
            pixbuf = icon_theme.load_icon("user-info", 32, 0) # Some icon.
            usrImg.set_from_pixbuf(pixbuf) # We set the image widget to load icon form a pixbuf.
        except gobject.GError, exc: print "can't load icon", exc

        userLabel = gtk.Label("User")
        self.userEntry = gtk.Entry(20)
        self.userEntry.connect("activate", self.changer, self.userFill)
        hbUPart.pack_start(usrImg,    10)        # A nice icon.
        hbUPart.pack_start(userLabel, 10)        # A label which says user.
        hbUPart.pack_end(self.userEntry )        # And the entry to enter the user name.

So if the full code can't be converted to pyqt, what other options can I consider ?

What I believe is I can almost fully convert the code if I know the path of the current theme, so when I know that constant, I will learn then the Open Desktop naming standards, and I will take the full path of the icon.

I'm just asking here for a more standard and easier way, if no such thing exist in pyqt, than I'll do this manually .

What about just using wxPython? I believe it has qt and gtk backends already so you don't even have to worry about it

That's the first time I heard about a wxPython/wxWidgets qt backend. IMHO wxWidgets has only a gtk backend. Maybe I missed something, but I couldn't find anything about it on google.

Edit:
As for the gtk-qt same look. I think gtk enables you to use different theme/application (see chromium browser), so maybe you could use gtk-qt engine or whatever other solution. I'm not that familiar with qt, but I think there is an option, so qt apps look the same as gtk ones...

Sorry, I was under the impression that wx could use qt as a backend but it does appear that I am mistaken.

I thought on that, but I want to practice pyqt.

The goal is to use the DE libs only, not to load gtk or qt lib if the opposite DE is on.

I've been doing a little research to try to make up for my mistake (actually more cause I'm bored) and no guarantees but I think your problem may be that the package is out of date. The documentation you reference is for pyQt 4.7, the version in extra is 4.6.2.

Someone else told me that yesterday, but I need than a workaround, I devised one, what I need is to get the full path of the current theme.
This is the idea, I grep-ed around the conf files and I dug this> ~/.kde4/share/config/kdeglobals, where the current icon theme is:

[Icons]
Theme=oxygen

with this code:

cd "~/.kde4/share/config/"
for a in *; do echo "$a:"; cat "$a" | grep -H "oxygen"; done

With the structure of the file I bet it's an ini file.
So, I made this little module:

#!/usr/bin/python
# -*- coding: utf-8 -*-

That module finds the current theme and index all the icons, than let's you find an icon by name, returning it's full path.

This is the test pyqt gui I made:

#!/usr/bin/python
# -*- coding: utf-8 -*-

from sys import argv
from sys import exit
from PyQt4 import QtCore, QtGui
from themeIconFetch import getIconPath

class qtGui(QtGui.QWidget):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)

        self.gct=getIconPath() # Theme index.
        icon = self.gct.getIcon("face-wink","16x16","png")
        if icon:
            winIcon = QtGui.QIcon(icon)
            self.setWindowIcon(winIcon)
        self.setWindowTitle(u"::\ Login /::")
        self.resize(400, 150)
        self.center()
        self.loginWindow()
    def center(self):
        screen = QtGui.QDesktopWidget().screenGeometry()
        size =  self.geometry()
        self.move((screen.width()-size.width())/2, (screen.height()-size.height())/2)

    def loginWindow(self):
        vbPole = QtGui.QHBoxLayout()
        hbKPole = QtGui.QHBoxLayout()

        # The image
        self.loginImg = QtGui.QLabel()
        iconp = self.gct.getIcon("user-identity","32x32","png")
        if iconp:
            icon = QtGui.QPixmap(iconp)
            self.loginImg.setPixmap(icon)

        # The label
        self.userLabel = QtGui.QLabel()
        self.userLabel.setText(u"User")

        # The input
        self.userInput = QtGui.QLineEdit()

        hbKPole.addWidget(self.loginImg)
        hbKPole.addWidget(self.userLabel)
        hbKPole.addWidget(self.userInput)

        vbPole.addLayout(hbKPole)

        self.setLayout(vbPole)
if __name__ == "__main__":
    app = QtGui.QApplication(argv)
    qb = qtGui()
    qb.show()
    exit(app.exec_())

Hope someone can improve my theme digger while still no news about pyQt 4.7 in extra.
