Here I will give you a list of the main features used in NatTable and for which I would like to know if they already exist in Calc and if there is an API (in Java ?) to drive them: - Customize the cell appearance with CSS
No.
- Manage the cell contents
Yes.
- Manage the cell access (read-only or read-write)
Yes.
- Declare custom cell editors (or dialogs) on cells to edit their contents
No. However, validity criteria and selection lists can be created for cell input.
- Show/hide columns or rows (not a deletion)
Yes.
- Display data as a tree in a column (with expanding, collapsing and hiding intermediate row without to hide its children)
Not sure what you mean, sounds a bit like Grouping or Pivot tables, you'd have to see yourself.
In addition, I would like to know if the toolbars and the menus can be customized and hidden easily.
Yes. Whether it's easy or not depends on your mileage..
Concerning the cell management, in the NatTable widget we proceed in 2 steps : - One step to declare the cell contents : we declare the java object represented by the cell. It is not a string at this level, it is a java object, like a list, a Boolean, an integer, ...) - The second step calls a LabelProvider which returns the text to display for the given object Is it the same kind of process in Calc or it is only a text management ?
Calc has numeric, text or formula cell content. Content/results can be formatted for display using styles, number formats and conditional formatting. Java objects can't be set as cell content.
So, to resume, my main question concerns the customization capabilities of Calc to manipulate its behavior programmatically. At the end, please, could you indicate me where I can found developer documentation about Calc and its API.
