Re: [PyQt] lambda slot problem
Ok, reading about the scoping problem with lambda i now understand the problem, activated it is the bool emitted from the clicked signal so i have changed it to: lambda activated, m=msg: self.changeStatus(m, activated) and now works correctly, thanks Brian. If i have understand the way that lambda works i should define inside the lambda expression any variable that i am using in the call and can change in the future, no? Regards, Miguel Angel. Brian Kelley escribió: You are seeing a scoping issue, to be safe, I would write the lambda as follows lambda changeStatus=self.changeStatus,m=msg,a=activated: changeStatus(m,a) This ensures that the bindings of self, activated and msg are what you expect when the lambda function is executed.

[PyQt] [PyKDE] kioslave example?
Hello, i wanted to make a simple kioslave for the following disadvantage: I have to directorys /files/backuped /files/notbackuped And now i want to make a kioslave myfiles:// that displays a folder which consists of the content of both /files/ directories. Writing support for the slave isn't necessary (in the end it should pop up a dialog that asks you if you want to backup the files). Are there any simple examples for a similar task? I only found the API reference for PyKDE4.kio.KIO.Slave, but that doesn't really help me. Thanks for any help, Lukas ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Re: [PyQt] selection behavior of a TableView

I'm using: View: QTableView Model QAbstractTableModel Delegate: QItemDelegate What I want is to change the Shift selection behavior of my TableView. Here an example: What I get when selecting 1/1 shift 2/2 : - 1 2 3 4 1 x x 2 x x What I want when selecting 1/1 shift 2/2 : - 1 2 3 4 1 x x x x 2 x x That is (AFAIK) not supported as you can only choose between whole rows or only items to be selected. So you'll have to implement either a custom view or try to do this by listening to selection-changed signals from the selection model and then modify the selection everytime the user clicks...
