Controls

Eto.Forms comes with a standard set of built-in controls that work across all supported platforms. Controls can be subclassed to override or implement behaviour. Each control has an implementation for each supported platform, which can be customized or replaced entirely if a particular implementation is not suitable for your use.

Custom controls can either be composed entirely of Eto.Forms controls, which would work across all platforms. If you wish to create a more complex control, or use functionality of a platform that isn’t exposed in Eto.Forms, then you can create your own custom controls with implementations for each platform (see Custom Platform Controls).

The standard controls are:

  • Button - Standard button with text
  • Calendar - Calendar control to pick a date or range of dates
  • CheckBox - Check box with a label

Containers

Container controls act as a control and can be added as a child to any other container. The layout controls supported are:

  • Panel - Controls that subclass Panel, such as Window, GroupBox, Scrollable, etc allow you to specify a single child Content control
  • TableLayout - Similar to how an HTML table works, with a single control per cell
  • PixelLayout - Specify X,Y co-ordinates for the position of each control (from Upper-Left)
  • DynamicLayout - Dynamic hierarchical horizontal and vertical layout
  • StackLayout - Horizontal or Vertical list of controls

Containers are implemented so that you do not need to specify a size for the container (although you can if you want). This allows containers to automatically size to fit the child controls, which works nicely across different platforms.

For example, if you created a Dialog or Form and didn’t specify any sizes for any controls, it should automatically size to fit its contents.

Windows

  • Form - A modeless window
  • Dialog - A modal dialog with no result value
  • Dialog<T> - A modal dialog with a custom result value
