Hello Folks,
I am working on a custom widget which will consist of a table (grid),
titlebar (header) and a pagination control (footer). The way I thought
to implement it is extend a composite and then add multiple (3)
composites to it for these 3 sections.
I am very new to SWT/JFace and have run into an issue: The 3 sections
get displayed fine but the contents of those composites (lable in
titlebar and table in middle composite) do not show up when I run. I am
pasting the code snippet below. Please let me know what am I doing wrong ?
Also, the reason why I am creating this custom widget is because we have
to reuse this datagrid widget many times in our plugin (with different
models) and we are trying to design a reusable component. Please advice
if this is the right approach or am I missing something.
Thanks,
Arpit
