Hello,
in my application I have some key handlers which receive input from
the user. When the user press a key,
a task has to be executed: this task could require a tiny time slice
or a longer one. The problem is that if the user
hold pressed a key and the relative task takes a lot of time to be
executed, my application will be flooded of key pressed events.
I would like to avoid the situation where I receive a lot of "key
press" events, which force my application to execute a long
time consuming task each time the event is received, and then the
application is stuck until all the events are "eaten".
How to avoid this? maybe i could delete the keys' event from the
events queue? Any help?
Actually I did a workaround for this problem:
1- get an key press event;
2- disable key press event with: set_events (get_events() ^
Gdk::KEY_PRESS_MASK);
3- start a timer which every 10 millisecs do a task;
4- receive a key release event;
5- stop the timer
6- reenable the key press event mask: set_events (get_events() |
Gdk::KEY_PRESS_MASK);
The problem actually is that I cant call "set_events" on a widget which
is already realized, and I am get a lot of warnings indeed.
So, my problem is still unresolved. Anyone could help me?
Thanks in advance,
Luca
p.s. I am using gtkmm, but there is no problem in talking to my about gtk+.
