You need LiveCode 8.1.10 or LiveCode 9 to use these widgets.
For a start you could use the free Community edition if you are downloading the open source widgets (marked with a *).
1 Start LC 8/9. 2 Download the
extension file (.lce) 3 Install the widget by selecting the lce file from menu
Tools/Download Manager and its button "+" at topright. 4 Quit and restart LC 8/9. 5 Download and open the
sample stack
widget.datepicker version 1.1.0 [-hh fecit 2018]
Instead of step 5 above you may also use
"go stack URL" from the LC message box.
Paste in LC's msg to load stack into RAM.
Thanks to Bernd Niggemann for valuable hints and comments.
Main Features and Hints
For creating new standard widgets ...
... Choose from menu Object/New Widget or
... DoubleClick the Date icon in Tools.
... Dragging from Tools does NOT work (is an IDE bug),
OR use it, without creating, as popup.
Use as popup widget (a modal dialog), see also the sample stack:
You have to give at least one argument: The date to display as year, month, day. Optionally you can give 33 more properties (of which 10 are colors and 8 are styles for different eparts). Especially can you
set the naming to english, system or custom,
start the week on saturday, sunday or monday,
see the lunar phase of the picked date and
scale the widget to 80-280% (done by affine transform).
For the standard widget you have 36 options available (additionally grabbing and a default pickerScale for use in the property inspector).
After installation of the widget and restarting LiveCode find detailed help in the dictionary.
