So the issue is if the combobox of the row is open (pop'd up) and I update the progress bar value self.store.set(iter, 2, self.core.progress ) Then the combo box immediately closes, if the update happens a couple of times a second the combobox is useless... Is there a way to update the progress bar without causing the combobox to c...

Simple question, but I can't seem to find the answer anywhere online. How do you use a custom TableCellRenderer to render some of the table cells in boldface?

Is there a comparable mechanism to the .NET "set DisplayMember" for the JListBox Swing component? Overriding the toString() method is not sufficient because I also want to be able to change the display member at runtime. I also looked into implementing my own ListCellRenderer, but found it not very convenient. Ist there a easier or mo...
I want to create a table which displays in each row a set of data, in addition to a radio button for possible selection.

Hello! In my PyGTK application I currently use 'editable' to make cells editable. But since my cell contents sometimes are really really large I want to ask the user for changes in a new window when he doubleclicks on a cell.

Hello, I was hoping someone could explain something to me as I found my solution, but I don't understand why it works. I wanted to set a default renderer by Class type to a whole table, not knowing at creation where objects will be in it. I had declared a JTable and set the default renderer to that of my own, for the Calendar class so...
When I have a gtk.CellRendererText, I can associate its foreground color with one of the tree store's columns, and set the foreground-set attribute to True, to change the color of the text in that column. However, when the row with the colored column is selected, its color disappears, and is the same as any selected cell's color. How do ...
I have a JTree and I am trying to have a customized look and feel to it, but I am having problems with my cell rendering.
