Custom container class for replacing and extending the VFP header class
The goals of this project are:
-
Allow 2 or more levels of headers per column. These custom headers can also be merged with one another.
-
Provide a more intuitive operation and interface for the grid's lock columns feature.
-
Address the flaw: a column can't be moved after having been locked.
-
Resolve the problem: user can unlock columns by right clicking with their mouse.
-
Support Theme (new for ver 2.1 or later)
