Re: How to update the interface?

[Bob Caryl <bob fis-cal com>]

Hello Mert:

"In my interface, I have button that is used to process an image. Since 
the process takes some time, the button is either left pressed, does not 
pop back during process or nothing happens. Is there any way to finish 
updating the interface first then finishing the call to a function?"

With regard to your first question: put the following at the beginning 
of the callback slot connected to your Gtk::Button::signal_clicked().

////////////////////////////////////////////////////////////////////
// code that allows the UI to update
while(Gtk::Main::instance()->events_pending())
Gtk::Main::instance()->iteration();
///////////////////////////////////////////////////////////////////

This will allow the UI to finish the button animation before you proceed 
with whatever the callback slot does.

"Also I have a textview widget I use in my application to show the user 
what steps are taken during the process. During the process, it doesn’t 
update (or print the text buffer) the textview widget also. "

Insert the foregoing code into the processing function immediately 
following your update to your Gtk::TextBuffer widget.

"Lastly, I would like to use the textview widget pretty much like a 
terminal. For example, how can I do like: textview_object << “string” << 
an integer << an stl vector << endl; so that I can print my stl vector 
variables or integers etc. "

See the docs

for information on how to use the Gtk::TextView widget.
