Hello all,
I'm not sure if this is a failure on my part to understand how GTK works, or a
series of unrelated
bugs, or a series of related bugs.
I have an application which needs to dynamically create a Widget. Once it's
created, every few seconds it
has to update certain parts of the widget - set some text, change some
background colors, change some
tooltips, etc.
BUG 1 - Removing widget:
I first tried to simply re-create the entire widget from scratch every
time. That should certainly have
worked. The problem is, when I did self.remove(widget), the application
would freeze. I thought, maybe
the widget is too complex to remove, so I decided to update certain parts
specifically.
Updating the labels by changing their text works fine.
BUG 2 - modify_bg:
Like I said, set_text works well. I, however, need some labels with bg
colors, so I placed some of them in
EventBoxs. When I create the widget, calling modify_bg to set the initial
color works fine. When updating
it later, any call to modify_bg causes the app to freeze.
I now belive bug 1 might have also been caused by this.
BUG 3 - tooltips:
The tooltips have to change in between updates. This works totally fine.
However, if the mouse is currently
hovered over a tooltip and the widget updates, the app freezes.
BUG 4 - adding widgets:
Some updates require an extra button to be added or removed, for example.
Adding a button once the widget
is initially created and attaching it / packing it into a container causes
the app to freeze.
Is there any function call, such as "please freeze the entire app and cancel
all events while I update the
widget" and then a correspodning "OK, wake up and use those changes" ?
Or is there a better way to do these things?
Thanks for any help. If I don't get replies I'll file 4 separate bugs in
bugzilla.
