QTabWidget SLOTS & SIGNALS
Message 1 in thread
Hallo,
I have a doubt about how are managed the connections between signals
from a QThread and the Slots in a QTabWidget.
I have a QTabWidget with 12 tabs, in each tad I have Widgets that are
enabled and disabled constantly with a signal from a QThread. (Each
widget in the tab has its own thread to be manipulated).
My doubt is that if meanwhile the user is seeing one tab, the enabling
and disabling of the rest of the widgets is still happening even when
the user can't see them. If yes, does this means an increase of useless
memory consumption and could this slow down the GUI?
In each tab exist 8 widgets that are manipulated by a thread, so in the
worst case, it could happen that 88 unecesary actions are running,
becuase the user dont see them?
Is that true? Do I need a function something like void
myGUI::just_do_what_user_sees?
Regards
David
