[PyQt] hidden signals?
hello, sorry for the tons of beginner-questions and thanks for your patience. there is a strange behaviour of a pushbutton and do not see, why it is ... there are two buttons and two lineedits. if the first button is clicked, only the first lineedit should be alive if the second button is clicked, the user should insert some data first in the first and then in the second lineedit. the program seems to pass the first-lineedit's slot correctly, but after that it runs through the first-button-slot, i never told it to do so !!?? I remember Java to have lots of builtin FocusEvents, but I do not think that this is the problem here. Can you give me a hint? Thanks a lot Merry Christmas jochen output: btn2_Clicked !Modus_firstButton edit1_ReturnPressed, !Modus_firstButton btn1.has NO Focus # btn1_Clicked#??

sorry
You could have stripped down that code a bit more, but its easy to see
the problem, now that I can run it.
Andreas
to see what is going wrong, please
1. click list
2. insert a number in the left lineedit
3. press return
now the right lineedit should have the focus.
The problem is that the Interactive button is the default button in
the dialog, so it automatically gets activated on return-presses.
Changing from QDialog to QWidget fixes that, I don't see a way to have a
Qt4 QDialog without a default button, though. Using setDefault on the
push buttons doesn't seem to do anything useful.
Andreas
If a dialog must be used, you can override the accept()-Method and handle the
Return press there. E.g.
if (focusWidget() == leftLineEdit) {
rightLineEdit-setFocus(Qt::OtherFocusReason);
return;
}
QDialog::accept()

Detlev

[PyQt] qtable object
Hi all :) I would like to be able to select a qtable object in order to copy and paste it in a sheet for example. Qtable is Qtdesigner made. when I select all, only last cell is copied.

[PyQt] Using a protected slot (columnResized)
Hello, I want to know when the width of columns in a table has changed. So I wrote something like this: class TableView(QtGui.QTableView): def columnResized(self, column, oldWidth, newWidth): print 'columnResized(%r,%r,%r)' % (column,oldWidth,newWidth) QtGui.QTableView.columnResized(self, column, oldWidth, newWidth) I then used my TableView instead of QtGui.QTableView. However, the method isn't called when a column is resized. Did I do something wrong? Should it be done in another way?
