View 6 RepliesI have looking for a tutorial or class that demonstrates more than a trivial example of saving a windows position on closing. The ones I have found don't seem to work on all systems because of:
1. Multiple monitors. (and resolution between those monitors)
2. Toolbar size and position (toolbar is only on the primary monitor, well sometimes)
3. Sometimes the programs dont open on the right monitor they were closed on.
Is there an extensive class or tutorial on all the stuff a programmer needs to get right to have a window size and position persisted between executions?
