Named GadgetData

Post by mk-soft »

With GadgetData can unfortunately only assign a value to a gadget.
But sometimes you want to store multiple values (Properties). For this, the values are stored in a map.

Update v1.03

Update v1.04
- Added CloseWindowEx(...)

Update v1.05
- Added check for remove panel item
- Added InitGadgetData(event) for Mac OS. On Mac remove internal GadgetObject with next (Wait)/WindowEvent

Here's an example with a BindGadgetEvent for the Calendar gadget

Code: Select all
