Note: You cannot modify a system palette. You can copy a system palette and modify the copy.
Before adding a class, refer to Class Requirements and Limitations.
This places a checkmark in the box indicating that the class is selected.
Warning: Clicking on the box next to a package name selects all of the classes in that package. If you choose to do this, be aware that you may adversely affect the visual builder's start up performance. Also, if you include too many classes, not all of them will be visible on the palette.
Warning: Keep all currently imported classes checked. Unchecking them means that they are removed from the palette when you click Update.
A dialog opens and displays the progress of importing the selected classes onto the palette. Classes that don't meet the requirements are not imported and a message states that they were omitted.
Clicking Update also saves your changes.
This removes the checkmark in the box indicating that the class is deselected.
Older (pre 2.2) palettes are not compatible with 2.3 and later releases due to changes in the palette file format. If you attempt to use older palettes, they load without problems but you may not see all of the associated events and methods.
There is a way that can salvage your older palettes.
If you are not sure that a palette has been updated, look at the top of a palette file with a text browser (like 'more') and check the header section to see if it was generated from cosmocode 2.2.
