I have been trying to display financial information using SWT because I
got fed up with the limitations of the spreadsheet and charting software I
have. So far, I have been able to open a window with a title, axes, key,
and drawing region set up relative to each other using a FlowLayout. It
looks ok, but I can't zoom in yet.
I want to implement the ability to drag click across part of the chart,
and have it box in the drag area into which the chart would zoom. I can
manage the code for only drawing that partial region, but I wanted to
figure out how to add the whole drag-click support to the GUI. Could
somebody suggest some things I should look into?
