Form Editor - SpinBox - Field Help

Form Editor - SpinBox - Field

SpinBox - Field is designed to handle integer values.

It allows the user to choose a value by clicking the up/down buttons or pressing up/down on the keyboard to increase/decrease the value currently displayed. The user can also type the value in manually.

This control is bound to the table field and allows the user to edit its value. The names of these table and field are shown inside of the control in the design mode.

The current value of the spinbox is taken right from the field and each change is applied immediately to the field.

Widget

  • Auto Fill Background – This property holds whether the control background is filled automatically.
  • Enabled – Defines whether the control is enabled or not.
  • Font – This property holds the font currently set for the control. The default depends on the system environment.
  • Palette – This property describes the control's palette.

The palette is used by the control's style when rendering. The color roles from this palette are combined with the control's default palette to form the control's final palette. The default depends on the system environment and may be different on different platforms. Control propagates explicit palette roles from parent to child. If you assign a brush or color to a specific role on a palette, that role will propagate to all the control's children, overriding any system defaults for that role.

  • Tooltip – The tooltip text.

Layout Item

  • Alignment – Defines both the horizontal and vertical alignment.
  • Expand Horizontal – If ON the control is expanded horizontally.
  • Expand Vertical – If ON the control is expanded vertically.
