This macro is to be run from the Calc program.
How does it work?
When the user starts the macro, a dialog is opened:
The user insets values for the upper and lower triangles, and clicks the submit button.
Then the macro draws two triangles in the cell selected. Each triangle is empty or contains a numeric value.
The program uses 3 main components:
- The spreadsheet document.
- A dialog.
- The draw-page part of the document, since graphics are not part of the cell contents. So, you would use a draw page to draw shapes.
The Code
This macro will create the dialog, add controls, and execute the dialog. A callback function will be attached to the submit button, and will draw the triangles.
Imports are not included; A link to the relevant data type will replace the import.
