Appearance

Default Button

The default button property designates the button that gets the initial focus at runtime when no button of the form has the Focusable property.

There can only be one default button per form page.

In addition, on macOS, the default button property modifies the button's appearance in order to indicate a "recommended choice" to the user and is automatically bound to the Enter key, even if it does not have the focus. The default button can be different from the focused button. Default buttons have a specific blue appearance on macOS:

Button must have a standard height to get the default button appearance.

On Windows, the concept of "recommended choice" is not supported: only the focused button has a different appearance at runtime and the Enter key is bound to the focused button. However, in the 4D form editor, the default button is represented with a blue outline:

Hide focus rectangle

During execution, a field or any enterable area is outlined by a selection rectangle when it has the focus (via the Tab key or a single click). You can hide this rectangle by enabling this property. Hiding the focus rectangle may be useful in the case of specific interfaces.

Hide selection highlight

Selection type list boxes

This property is used to disable the selection highlight in list boxes.

When this option is enabled, the selection highlight is no longer visible for selections made in list boxes. Selections themselves are still valid and work in exactly the same way as previously; however, they are no longer represented graphically onscreen, and you will need to define their appearance programmatically.

By default, this option is not enabled.

Resolution

Sets the screen resolution for the 4D Write Pro area contents. By default, it is set to 72 dpi (macOS), which is the standard resolution for 4D forms on all platforms. Setting this property to 96 dpi will set a windows/web rendering on both macOS and Windows platforms. Setting this property to automatic means that document rendering will differ between macOS and Windows platforms.

Show references

Displays all 4D expressions inserted in the 4D Write Pro document as references. When this option is disabled, 4D expressions are displayed as values. By default when you insert a 4D field or expression, 4D Write Pro computes and displays its current value. Select this property if you wish to know which field or expression is displayed. The field or expression references then appear in your document, with a gray background.

For example, you have inserted the current date along with a format, the date is displayed:

With the Show references property on, the reference is displayed:

4D expressions can be inserted using the ST INSERT EXPRESSION command.
