number of times in the form.

● ypos

combobox
The field displays the corresponding identifiers instead of numerical values.
If field type combobox is selected, the expressions to be displayed must also be
assigned to the field.
The <ITEM> tag should be used for this purpose.
The combo box saves the index of the currently selected text in the variable belonging
to the control (see the attribute refvar).
After the control has been created, additional elements can be inserted using the
functions addItem or insertItem.
– progressbar
A progress bar with a value range of 0 to 100 appears.
The valley value and peak value properties can be used to adapt the value range to
the data to be displayed.
