Hello,
I have some questions about signals and
functions.
When a certain event occurs on a widget, a function
is called with the widget-pointer, and a data pointer. But isn't this sometimes
a bit difficult?
Example:
a button widget is pressed, then i want to read
integer data from a spinner, and set the status widget to a
text.
Does this mean i have to make an array with 2
pointers in it, and give that as the data pointer?
Or should i declare the button, spinner and status
widget als local variable? (on top of the file) That way i won't use the
pointers i give with the function, but it's easier to program.
What's the best way to do
this?
