I'll look at your code and then try to understand what's wrong. If I find the answer, I'll send it here. So should you make improvements to it, please post it back. Indeed Erik, I'm working on a tutorial so as I'm doing my own project for editing math easily.

Hello, I would like to know if the pygments patch of the software Eric could be add to the standard PyQt distribution because the real weakness of QScintilla is the impossibilty to define particular lexer. It has nothing to do with PyQt. I have the patch but don't intend to make a new release of QScintilla just for that. That is fair and reasonable seeing the amount of work scheduled for sip and PyQt4. Meanwhile people can apply the patch, which is included in the eric4 package themselfs.

Hi,
I am having problem to get QSystemTrayIcon to work. I am running on

My setup: windows XP, PyQt 4.3.3, python 2.5
See my attached simplified code, that runs standalone. Any idea what I
could be doing wrong ?

[PyQt] Re : Signal and SyntaxHiglight
I would like to know if there is a signal sended by the SyntaxHiglighter when it catches a change in the text ? That class is designed to be subclassed rather than connected up with signals and slots, but you could emit your own signals when you handle the changes in format. Alternatively, you might want to look at the signals emitted by the QTextDocument object itself. These will tell you when the text has changed. The problem with this method is that a signal is emitted every time a change appears and not only when a word to highlight is typed.

[PyQt] Reach a line in a QTextEdit

Re: Re: [PyQt] Reach a line in a QTextEdit
The first method works very well. Thanks a lot ! Christophe. I would like to go for example to the fourth line in a QTextEdit. Is-it possible to do that directly or must I have to walk along the three first lines so as to go to the start of the fourth one ? Use either: 1. QTextEdit::moveCursor(), but you need a for loop to go up/down for multiple lines. Example: editor = QtGui.QTextEdit() [...] for l in range(4): editor.moveCursor(QtGui.QTextCursor.Down, QtGui.QTextCursor.MoveAnchor) 2. QTextEdit::textCursor() to get the cursor, then QTextCursor::movePosition() and then QTextEdit::setTextCursor() so that it takes effects. Example: editor = QtGui.QTextEdit() [...] cursor = editor.textCursor() cursor.movePosition(QtGui.QTextCursor.Down, QtGui.QTextCursor.MoveAnchor, 4) editor.setTextCursor(cursor) Regards, Cyril ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Your problem is with your OpenGL syntax. Simply change GL.GL_QUADS (which draw quadrilaterals) with GL.GL_TRIANGLES (self evident). Also, it would be better to move those declarations into your triangle routine as follows Thanks and sorry for this simple problem but I'm a real newbie with OpenGL.

Re: [PyQt] SplashScreen and mousePressEvent
Brian Kelley a écrit : The splashscreen is probably not what you want. You can make a QFrame and apply the following styles QFrame( parent, Qt.X11BypassWindowManagerHint | Qt.FramelessWindowHint | Qt.WindowStaysOnTopHint | Qt.Tool ) You will need to override the mouseClickEvent to close this window. To place it you can get the mouse’s x,y position when right clicking on the tree node and create the frame (with the appropriate images inside) and then place it appropriately.

Thanks, I'll try to understand that. Maybe my problem is a problem of

Best reagrds and a great thanks for your help.
Christophe.
Apologies for the C++ code, we have an info label that displays text
in a popup QFrame, this is the method that sets the text and makes the
widget visible.
The things you will find interesting are mapping from the cursor to
the current frame and then mapping this point (after moving out of the
way of the mouse) to the mainwindow (which is the parent of the Qframe).
Hope this helps.

{
if (s.empty())
{
if (!_hidden)
{
hide();
_hidden = true;
}
}
else
{
QPoint pos = mapFromGlobal(QCursor::pos());
setText(s.c_str());
adjustSize();
QPoint p(pos.x(), pos.y() - height());
move(this-mapTo(parent(), p));
raise();
if (_hidden)

Indeed the line

[PyQt] Searching for a very small scprit using CLIPBOARD
Hello,
here is an example for using the clipboard of Tkinter :
from Tkinter import *
root = Tk()
root.clipboard_clear()
root.clipboard_append('A text in the clipboard...')
root.withdraw()
I would like to do the same with PyQt. Is it possible ?
Christophe.
PS : if someone knows a Python script which is an universal ClipBoard
(ie which works on Unix and Windows), it would be better. The purpose is
just to send text.

Re: [PyQt] Searching for a very small scprit using CLIPBOARD
sys.exit(app.exec_()) doesn't work. If the clipboard is empty when the program exits, I
will do without PyQt so as to have a universal clipboard.
Thanks a lot because now I knows how to use clipboard in a real program..
Christophe.
Demetrius Cassidy a écrit :
The clipboard will empty when your program exits. Afaik this is normal
behavior with Qt and clipboard access.
I know if I use wxWindows the text in the clipboard stays even if I close my
app, however I am not sure if it's possible to do this in Qt.
And use sys.exit(app.exec_()) instead.

Re: [PyQt] Searching for a very small scprit using CLIPBOARD
Thanks a lot, your solution works fine. :-) Here is the complete
minimal code :
#!/usr/bin/env python
#coding=utf-8
import sys
from PyQt4 import QtGui, QtCore
app = QtGui.QApplication(sys.argv)
clipboard = app.clipboard()
clipboard.setText('The text that must be copied...')
event = QtCore.QEvent(QtCore.QEvent.Clipboard)
app.sendEvent(clipboard, event)
Aron Bierbaum a écrit :
We ran into a similar situation where we wanted to ensure that a
QPixmap that is copied into the clipboard stays after the application
exits. Although as far as I know this should happen automatically when
your Qt application exists, we had to do this use the following code
manually before exiting our application.
# Send an event to the clipboard so that it copies the data over to the
# clipboard instead of keeping a pointer to the data internally. This should
# happen automatically on exit, but it appears that the mime type convertion
# methods for Qt - windows formats get unregistered before this event gets
# processed. This caused a bug where we couldn't paste data after closing
# because there was not a conversion method. The magic function on
Windows that
# needs to be called to do this copy is OleFlushClipboard.
from PyQt4 import QtGui, QtCore
clipboard = QtGui.QApplication.clipboard()
event = QtCore.QEvent(QtCore.QEvent.Clipboard)
QtGui.QApplication.sendEvent(clipboard, event)
The basic concept behind this is that by default copying something
into the clipboard only copies a reference/pointer to the source
application. Then when another application wants to paste the data
from the clipboard it requests the data from the source application.
Calling OleFlushClipboard [1] causes Windows to copy the real data
into the clipboard instead of the reference. While this does cause a
delay when copying images, it should not have any noticeable impact
with strings.

I have a little program that have the text sent to the user interface

self.top_label = QtGui.QLabel(self.tr(label_text))
In fact this is some excerpt of parts of the code. What I want to do
is translate every word of the text to Portuguese. I tried simply
translating but then it gives me an error of outside ASCII range.
Then I added coding: utf-8 at the top of the file. Changed self.tr to
self.trUtf8 with no luck. I tried self.tr(unicode(Some text)) with
no luck too.
What I want to do is simply tranlate this program, I dont want it to
be internationalized, I mean, changing it in a way that it can be
tranlated again easily.
The Portuguese characters have é, ç, ê, ô, etc. I tried with
self.trUtf8 and putting the code in hex like this self.trUtf8(\00C9)
without success. I've read a lot of pages telling how to print unicode
characters but I couldnt print a single character right now.
If anyone can help me I will really appreciate, just to give me some

[PyQt] QSyntaxHighlighter and folding
Hello, I would like to know if QSyntaxHighlighter can work with folding. I don't think so but... Best regards. Christophe PS : Indeed I've tried to use QSciScintilla and its custom lexer but with no simple examples to start it becomes to be very boring to try to find an hypothetical clue.

[PyQt] QsciScintilla
H'ello, it is too hard to understand what it must be done sucha built with a custom lexer which could be recalled the harder lexer... :-) More seriously, I would like to know where I can do suggestions for a more easy use of it. There is a big incoherence to propose something so easy to use such as QSyntaxHighlighter and to propose a custom lexer with no example. I've already propose a simple lexer wich can be an instructive example for the C++ or Python newbies. This lexer would for example 1. ... put in red all line which begins with a # 2. ... put in blue only the word blue 3. ... make a folding with something starting with /* and ending with */ By doing this I'm sure that more people will use QScintilla because it would be easy to custom it. It seams that the users of Qscintilla are always the same and they don't seem to understand that the task for a newbie is very hard because all the examples are real ones and then there are a litlle bit complex to understand.

[PyQt] Re: [Matplotlib-users] Strange issue when using Matplotlib with PyQt4
Lukas Hetzenecker a écrit : I tried to embed a Matplotlib FigureCanvas into a QTabWidget. But at the first start of my script - the main.py in the attatched example - the widget in the Tab is incorrectly sized. If I embed the FigureCanvas in a QTabWidget the widget is to big, but if I put it in a QWidget it is shown correctly. I'm not sure that is a pure MatPlotLib issue. Have you try with a big standard widget instead of the FigureCanvas ? Christophe ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Finally I've done a very simple lexer that find multi-lines /*...*/ wich
can be folded and single line //... comment of C++ kind. I hope that
will help people and that there is no bug.
Thanks for all the informations. The next step would be to highlight

Hello, in some language like HTML there are PhP codes and/or JavaScript code embeded. It could be usefull to have a way to tell to Scintilla to use some specific Lexer for specific lines.

Yes it would be very great because compiling is not easy for all users. On Ubuntu, the use of Synaptic is easy even for noobies.
