TableView

[devilsclaw]

Hi,

I am looking to port a java application to nappgui, but the main part of the program has a table that has editable elements. I was wondering the status / progress of the TableView code and what all needs done before its functional. I have no problems contributing time and code to make it work either.

Thanks

Hello @devilsclaw! First of all thank you very much for considering NappGUI to develop your project.

Currently the development of the TableView control is stopped. Other priorities have been appearing, but this may be a good opportunity to resume its development.

The main drawback of this component is the great difficulty of creating a wrapper over the native controls (WC_LISTVIEW, NSTableView and GtkTreeView) so that they work in the same way on all three platforms.

On the other hand, the idea is to provide the NAppGUI TableView with total flexibility when defining the content of the columns/cells (Text, images, CheckBox, EditBox, PopUp, ProgressBar, etc).

For these reasons I made the decision to create a custom control in NAppGUI and discard the native controls. The first step was the creation of the ListBox control, whose drawing and management is done completely in NAppGUI from a View control. https://nappgui.com/en/gui/listbox.html

Give me a few days to study the case and recover the code that I have in my private repository. If I see it feasible, I will create a branch with the implementation of the main skeleton of the component. If you have time and can work out some details, that would be a great help.

We are in contact, Greetings
