Form Editor - Image - Field Help

Form Editor - Image

The Image - Field control is used for displaying an image stored in the BLOB/Picture field or loaded by the URL (e.g. 'http://example.com/image.png') stored in the textual field. The Image control is used for displaying an image. No user interaction functionality is provided.

Properties

  • Field – The name of the bound field or empty if a field was not defined.
  • Name – The name of the control.
  • Frame – If ON the control will have a frame.
  • Scale – Defines whether the image size is adjusted to the control size or not.

Form Editor - Image - Field Properties

  • 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.
