Re: Detecting if a column has been resized by the user;auto-stretching columns.

David Boddie — 2008-12-04T00:07:56

Then there is a solution. It's quite well hidden: tableWidget.horizontalHeader().setStretchLastSection(True) It's the header that handles the width of each column, which is obvious if you think about tables in a certain way, but it seems to catch a lot of people out. David

Re: Detecting if a column has been resized by the user;auto-stretching columns.

Anonymous — 2008-12-03T17:10:00

Thanks for the response, but i saw that in the documentation before asking, and it's not what i'm looking for. The columns for my purpose do not need to be fully stretched out, i just need the last column in the view to auto-stretch if there is space for it to take up. Since QTableWidget does not by default support HTML, i had attempted two methods into getting it to display HTML. The first was subclassing QItemDelegate and QTableWidgetItem. The other was setting a QLabel as a table cell's widget. However, both of them have undesirable consequences which i have been trying to solve. The common undesirable consequence is that both attempts do not give the proper (i believe) size hints for the table cell, so double-clicking on the row's or column's edge causes an inaccurate resize. In attempting to detect if a column has been resized by the user, i thought tableWidget.__class__.columnResized = self.columnResized would help, but it didn't. The reason why i need to detect if the user resized the column

Re: Drag status message

David Boddie — 2008-12-03T01:09:41

OK, sounds good so far. Have you tried calling self.statusBar().showMessage() instead? If the above suggestion works then I have an idea why self.setStatusTip() does not; otherwise, some more investigation will be required. :-) exec_() is creating an event loop, but events should still be delivered to the window. It could just be that changing the status tip on its own isn't enough to display a new message. David

As in rendering them without creating new group boxes or actually creating as many group boxes as you need? David

Display and image in qtreewidgetitem?

Christian Aubert — 2008-12-02T22:29:39

I'm trying to display an image as part of a qtreewidgetitem. Figured I'd use setIcon and then resize it but when I run this bit of code: icon = QtGui.QIcon()icon.addPixmap(QtGui.QPixmap(thumbnailPath), QtGui.QIcon.Normal, QtGui.QIcon.Off) reportUI.setIcon(0, icon) reportUI.setIconSize(0, QtCore.QSize(240, 120)) I get this error: Traceback (most recent call last): File "Z:\_USERS\Christian\work\odTools\src\odToolsDlg.py", line 1982, in on_report_CreateButton_clicked reportUI.setIconSize(0, QtCore.QSize(240, 120)) AttributeError: setIconSize I believe this should be valid, any ideas? Or is there a way to display an image in a qtreewidget? Christian Iliya Gogolev wrote:

Oh yes: subprocess is absolutely useless on Mac with threading programs (QApplication probably creates a thread behind the scenes): http://bugs.python.org/issue1068268

QProcess

Matt Smith — 2008-12-02T15:25:18

This answer in no way addresses Qt. If you want to execute a file in unix and it is not in your path you need to specify its location. hence './pippo'. You could also type '/my_dir/pippo'. so if you can type '/my_dir/pippo' and it executes pippo from the terminal. then you can use that for your QProcess. mbs

Hello i have a little problem. If i start the process like the sample all work: pr = QtCore.QProcess() pr.start('python /my_dir/pippo.py') but if i compile the pippo.py and i obtain an executable that i run with ./pippo how i have to do fur run it with qprocess? I have try with pr.start('/my_dir/./pippo') and nothig work i have also try with pr.start('./ /my/dir/pippo') and also in this way nothing start. can you tell me please the correct way to start this process? Thanks Luca

2008/12/1, Michał Andrzej Woźniak yahoo.co.uk>: It has to run on Linux/Win/Mac :) And it has to work nicely with QGtkStyle - looks native on GTK WMs. pykde4 is on my todo list to see what I can use. If KParts, KIOslaves could be reused easily without massive pykde code writting then who knows ;) Probably at v 0.5 all questions will be answered :)

Arbitrary number of copies of groupbox?

It would be a cool thing to be able to use KParts should one want to/like to. Anyway, just an idea for version 1.x. ;) Great! If there will be a possibility to "package" the widgets as KParts, it would contribute a lot to the overall KDE flexibility (one could use your editor widget as an alternative KPart in Konqueror or KWrite, and the "stats://" widget in Konqueror and Dolphin). Had I only the time, I would brobably dive into KParting those widgets myself... eh. Cheers mike
