Re: [PyQt] QMYSQL + QSqlQueryModel.
I have compiled mysql plugin with mingw it works with standard Qt installation. Sqlbrowser example from Qt demo works with my plugin ok and queries fetches data from database just fine! But I can't include my mingw compiled plugin to pyqt compiled by riverbank. Replacing C:\Python26\Lib\site-packages\PyQt4\plugins\sqldrivers\qsqlmysql4.dll with mingw compiled version didn't working. Even when I clearing Qt plugin cache in registry. QMYSQL just not showing in available drivers. It's because pyqt compiled with microsoft compiler from Visual Studio? How can I replace standard plugin with mingw version? How can i compile mysql plugin with Qt OpenSource SDK (without commercial license) and with Visual studio compiler? Configure.exe wants commercial license when I choose 'c' in his options. --- igor at tyumbit.ru ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
Re: [PyQt] QMYSQL + QSqlQueryModel.
Hello, my previous post didn't have any asnwers, so I'll try once again:
now I'm cutting my example to bare minimum (without models) it's still
behaves very strange:
My info: winxp, msyql 5.0.45, python 2.6.2, latest precompiled pyqt which
comes with mysql plugin as dll , qt 2009.3
Here is a script:
-
from PyQt4 import QtSql, QtGui
from PyQt4.QtSql import *
import sys
app = QtGui.QApplication(sys.argv)
db = QSqlDatabase.addDatabase("QMYSQL")
db.setHostName('localhost')
db.setDatabaseName('mysql')
db.setUserName('root')
db.setPassword('root')
db.setPort(3306)
for driver in QSqlDatabase.drivers():
print driver
if not db.open():
QMessageBox.warning(None, "Error log", QString("Database Error:
%1").arg(db.lastError().text()))
sys.exit(1)
query = QtSql.QSqlQuery(db)
print 'query result is:', query.exec_("select now()")
while query.next():
print "got something"
if query.lastError().type() !=QtSql.QSqlError.NoError:
err = query.lastError()
print 'databaseText error:',err.databaseText()
print 'text error:',err.text()
db.close()
-
And here is output:
QSQLITE
QMYSQL3
QMYSQL
QODBC3
QODBC
QPSQL7
QPSQL
query result is: True
databaseText error:
text error: QMYSQL3: Unable to fetch data
Couple of questons:
why QMYSQL3 in error? I'm accessing QMYSQL plugin.
why no data from mysql?
qt opensource compiled with mingw. mysql plugin which comes witch pyqt
compiled with MS compiler.
Should I recompile mysql plugin with mingw or with MS compiler? Or it
doesn't matter?
Thanks

[PyQt] QMYSQL + QSqlQueryModel.
Hello, I'm recently upgraded my python setup to

generally it's trying to show all logins available in mysql database.
Please see,that it's system database.
What I've got on the screen is a table with 4 EMPTY rows (no logins
displayed) and output on console: 'value not valid?' many times...
c\:mysql -V
C:\Program Files\MySQL\MySQL Server 5.0\bin\mysql.EXE Ver 14.12 Distrib
5.0.45, for Win32 (ia32)
c:\> mysql -uroot -proot -Dmysql -e"select user.user from user" shows
that's there is actually some logins
+--+
| user |
+--+
| igor |
| root |
| igor |
| root |
+--+
Could please someone check my script on his own mysql db?
Is something wrong with decoding/encoding my values which I receive from db?
or with mysql setup?
or with mysql plugin which comes with pyqt installation?

Put it somewhere in your main.py and you got nice messagebox when exception
occurs anywhere in your code.

Hello,
you could redirect the interpreter's standard error output stream:
sys.stderr = YourClass(window.edit, sys.__stderr__, QColor(Qt.red))
YourClass in an "file-like" object (it has an write function) window.edit is
an instance of Qt's QTextEdit class and is used to display the message.
Here is an example: http://series60-remote.svn.sf.net/viewvc/series60-
remote/trunk/pc/series60-remote.py?view=markup , line 288
The class QtOutput is defined here: http://series60-
remote.svn.sf.net/viewvc/series60-
remote/trunk/pc/lib/log.py?revision=257&view=markup , line 36
And the window that actually displays an error message is here:
http://series60-remote.svn.sf.net/viewvc/series60-
remote/trunk/pc/window/log.py?view=markup
A screenshot is here:
http://imagebin.ca/view/5rSa--2X.html
The Traceback is colored red in the window.
Starting with this is should be easy to get a "report bug"-dialog ;-)
If you have any questions please just ask.
Greetings,
Lukas

[PyQt] Detecting second copy of program in memory.
Hello, I'd like to detect if user tries to launch 2 copies of program.
First one should rise from minimised state, and second copy should
gracefully exit if detecting first one.
So user should see that he is already running program.
Here is my lame attempt (please see attachment).
Generally it works, but problem is:
I can not receive events until app.exec_() is called.
So second copy is showing QMainWindow object and _only then_ exits...
Just run main.py and then run it again not closing first one to see blinking
of second copy.
Is there a way to make it more clever way (not showing QMainWindow)?

RE: [PyQt] How to get an event after an Enter key is pressed?
I think QAction is the way to go:
something like this works for me:
delrecords = QtGui.QAction(self) # create action
delrecords.setShortcut(QtCore.Qt.Key_Delete) # set shortcut key for
that action
.addAction(self.delrecords) # assign action to
widget
self.connect(self.delrecords, QtCore.SIGNAL("triggered()"),
deleteRecords) # connect event is pressed in YOUR_WIDGET.

Subject: [PyQt] How to get an event after an Enter key is pressed?
I wrote an application where I display sql data on a
QTableView+QSqlQueryModel read only table.
The current version allows you to select via mouse a record on that table
and then add it to an other one, pressing an add-button.
I'd like to give an alternate way to do this: after record line is selected
on the table I'd like to be called on the pression of enter's key and react
to it just like if the add button was pressed.
If is possible to obtain this behaviour I'd like to trap an other button
too:
I'd like to be called when delete's key is pressed while the record line is
selected.
Thanks in advance for your help.

[PyQt] Wrapping style classes with SIP for styling python application.
Hello, I'm trying to wrap unwrapped classes for styling my application. Well, seems it's not so trivial. I have managed successfully rebuild PyQt from sources with new wrappers for QCommonStyle,QMotifStyle But when I'm trying to overload method QMotifStyle.polish for example my application is crushed with access violation class NorwegianWoodStyle(QMotifStyle): ... ... def polish(self,palette): print "start" print "when finishing this line, app is crushing" def somethingelse(self) ... Actually I'm converting ..\Qt\4.3.3\examples\widgets\styles\norwegianwoodstyle.cpp to python. I'm suspecting that there is error in my hand coded QCommonSytle or QMotifStyle.sip somewhere. May be I didn't specify some SIP annotation for some method somwhere deeep in class hierarchy. I don't have much expierience with SIP files, actually it's only 2 days :). So the question is: Phil, can you generate those SIP files with your MetaSip package which is not available tо wide public and put them somewhere as separate package with note: "use on your own risk, I'm not officially supporting those files, because styles in Qt can be compiled like plugins and I'm not gonna supply them with main PyQt branch because of that, but if you brave enough than go ahead" If that's not possible than can you look at my hand coded files and tell me where I'm wrong? I will attach my files if overall effort have any sense. Because I spend a whole weekend ont this task but with not much success. >From time to time in mailing list I see that peoples are trying to do what I'm trying to do now: 'Made custom skin with python' I know about StyleSheets. And I have read that it's kinda slowww... So I will try to stick with overriding built in style classes and wrapping unwrapped classes. Sorry if I'm asking to much or if you can't (or wouldn't) do that I'm really appreciating you great PyQt package. --- Igor.

[PyQt] QComboBox + custom model, view, completer fails.(with example)
Hello,all!
I'm trying to build my own completion in QComboBox.
My overall setup with this thing is not working.Apparently I'm doing
something wrong here.
But what?
What I'm trying to do:
let's suppose we have this completion list (for simplicity it's small and
with one column only,
real data have much more columns).
So items goes like this:
- item1
- item11
- item111
- item
if I type '111' in QComboBox I want a popup with 'item111','item'
because '111' is only in those items.
I'm defined my own TreeView,SourceModel, SourceFilterModel(like proxy for
filtering of SourceModel) and bind them
to standard QComboBox.
Than I did a little trick with passing focus to lineEdit and back to Popup.
Well, my whole schema is not working.
Python recursively calls 'somethingIsTyped' method in which I'm trying to
force popup to be filtered and
shown with new data and I got stack overflow catched by python interpreter.
Please see attached example with comments.
Can anybody enlighten me on what I'm doing wrong?

Yeah, I'm agreed on that, I just wanted to provide my own custom skin for user to decide which one to use. When creating skin I want to subclass from ready skins.(like Motif for example) C++ code in Qt example which is based on MotifStyle seems not very hard to convert to python. But creating own custom skin from scratch in python is a lot more work.

RE: [PyQt] QtGui.QMotifStyle not in PyQt?
Hello, Ulrich, nice to hear a response again from you :) I know about style sheets. Well, I'm not sure that I have a full control over the widget, when using style sheet. Also I can not find any widely available applications which utilises this feature, and looks cool and stunning. May be someone can provide a link or maybe screenshot? I'm interested in details of this feature. Example of style sheets in qt docs with student registration window is not very impressing. --- [EMAIL PROTECTED] ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] QtGui.QMotifStyle not in PyQt?
Hello,all! I'm looking in styling my pyqt application. There is nice python "styles" example ported from C++. But it's not complete port because NorwegianWood style is missing. In original C++ demo this example shows one more custom style build by user. So I'm digging deeper and find that QMotifStyle on which this NorwegianWood style is build is'n ported to python part. Is it done intentionally or it's just technologically hard to do? Or it's licensing issues? I'd like to build my own style for application. And second question: anyone of you guys use custom themes like NorwegianWood for example? Do you build your own or just use embedded in Qt? (plastic, cde, etc..) Also how can I build QtDesigner package in order to use custom widgets in design time? May be there is binary build somewhere? My info: winXP, python 2.5, PyQt 4.3.3, Qt 4.3 Open Source Edition.

RE: [PyQt] Locale problem with dateEdit calendar popup (Solved by Ulrich!) :)
Thanks, Ulrich. Your solution is really helps me! Now everything is working as expected! Monday goes first in sample.py Unfortunately my pyqt installations (4.3.3) doesn't have PyQt4.QtDesigner package. I've remember reading somewhere in this list about this package " it's statically linked, you should build it yourself" or something ... Such a pity that I could not install custom plugin in Designer out of the box. But datetimeedit.py gives me good example and possible solution. I think I can proceed with that. Big thanks again! :) --- [EMAIL PROTECTED] ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] Locale problem with dateEdit calendar popup
Hi there,
I have dateEdit input widget with calendarPopup set to true.
Underlying calendar widget shown and first comes Sunday,than Monday,then
Tuesday etc..
here in Russia we counts weeks from Monday,Tuesday etc...
I've discovered in docs this method:
QCalendarWidget.setFirstDayOfWeek(Qt::DayOfWeek dayOfWeek).
So this underlying popup calendar is tweakable.
Question is: how get this object from dateEdit control?
is there something like:
mydateEdit = QtGui.dateEdit(bla bla bla)
mydateEdit.getQCalendar.setFirstDayOfWeek(Monday)
^^
How can I access underlying Qcalendar popup in dateEdit in order to set his
properties?
Or may be there is global locale setup for Qt application by default?
I have in my code those lines:
from PyQt4 import QtCore, QtGui, uic
import locale
locale.setlocale(locale.LC_ALL,'Russian_Russia.1251')
# setup global python locale for regexp etc...
QtCore.QTextCodec.setCodecForLocale(QtCore.QTextCodec.codecForName("cp1251")
)
QtCore.QTextCodec.setCodecForCStrings(QtCore.QTextCodec.codecForName("cp1251
"))
QtCore.QTextCodec.setCodecForTr(QtCore.QTextCodec.codecForName("cp1251"))
Please note that my popup calendar is localized - I mean I see cyrillic
letters,
everything is ok except this "our Qt week starts from Sunday he-he."
problem... :(
Can anyone of subscribers of this list from countries where weeks starts
from
Monday (Europe?) check in designer how this widget is shown?
Thank you in advance.
My platform: python 2.5 pyqt 4.3.3 gpl, windows xp.

Hi, Andreas! First of all, thank you for answering my question. > As far as I can see, what you need to do is to also provide "m10" as an entry in your completion model. Sorry,but my users can type anything and I have not possibilities to predict and add any possible combination of chars into completion list. So seems like Qcompleter is not intended for a job like this... May be I can work around with another widget. Btw, can I add some kind of custom popup widget to TextEdit control for example? --- [EMAIL PROTECTED] ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] Qcompleter,dateEdit popup questions.
Hello,everybody! I'm new to PyQt and in process of converting my application from wxPython to PyQt. I'd like to ask couple of question about nice QCompleter class in Qt and PyQt. Question #1: How can I build my own custom completer which completes on any char in the item word? It seems that default Qcompleter completes only if my items starts with letters that I've started typing. For example: here is my abstract model data: Item10 Item110 Item20 Item220 If I type for example 'm10' then completer should provide only 2 matches Item10 Item110 because 'm10' chars is found only in this two items. I've read documentation about QCompleter in Qt docs but can not find a clue about methods used by Qcompleter when deciding which item from model is matched to my typed word. I think I should inherit from QCompleter something like this: class MyCompleter(QCompleter): def __init__(self, parent=None): super(MyCompleter, self).__init__(parent) self.model = MyCompletionModel() self.setModel(self.model) self.setCompletionColumn(0) Now the question is : which method should I override in order to intercept QCompleter decision about which item from model is fit for currently entered text? Is there something like this? : def complete_decison_method(self,item): prefix = self.completionPrefix() # Get typed text which shoud be completed or matched. if str(item).find(prefix) == -1 : # no - this item don't match entered text, don't show it in popup return False else # yes! this item matches somewhere with prefix - it's valid to complete! return True Can someone provide hint or url maybe? I've read http://doc.trolltech.com/4.2/qcompleter.html but don't find enough info to answer my question. Question #2: I have a dateEdit widget with calendarPopup = true. When calendar chooser is shown in popup - week is started from Sunday. Can I have a dateEdit widget with popup where week is started from Monday? My locale is correct I think, so in calendar popup I am seen russian letters, so problem is not in locale setup I think.
