At the top of the window there are two lists: the first one displaying all objects on the form, while the second
one − the methods related to the selected object from the first list. Methods are the actions or tasks performed
by the given object (the control element on the form).
The code window provides control over the number of displayed procedures. For this purpose, two buttons
are provided in the upper right corner of the window:
– View all mode;
– View handler mode.
To add a new procedure, select an element in the list of objects, and then select the desired method for that
element in the list of methods. By doing so, an appropriate procedure will be added in the code window.
Example of Macro with Screen Form
Let’s review an example of a macro written in the Visual Basic programming language. Executing the macro
creates a segment between two 2D nodes. Coordinates of those nodes are entered via a dialog.
Initially, a form «FormLine» was created in the Project «CreateLine.grb», and then controls were placed on
it, which will be used for defining 2D nodes coordinates. Another control element was added to the form – a
button, clicking which would launch the function creating the 2D nodes and the segment between them.
