Méthodes publiques

Méthode Description
AttachNative ( ) : void

Attaches the control for direct use in a native application

Use this to use a control directly in a native application. Note that the native application must be running the same framework as the current platform. E.g. a WinForms application can use an Eto.Forms control when using the Eto.WinForms platform. This prepares the control by firing the PreLoad, Load, etc. events.

Control ( IHandler handler ) : System

Initializes a new instance of the Container with the specified handler
Detach ( ) : void

Detaches the control by removing it from its parent

This is essentially a shortcut to myControl.Parent.Remove(myControl);

FindParent ( Type type, string id = null ) : Container

Finds a control in the parent hierarchy with the specified type and Widget.ID if specified
FindParent ( string id ) : Container

Finds a control in the parent hierarchy with the specified id
Focus ( ) : void

Attempts to set the keyboard input focus to this control, or the first child that accepts focus
Invalidate ( ) : void

Queues a repaint of the entire control on the screen

This is only useful when the control is visible.

Invalidate ( Eto.Drawing.Rectangle rect ) : void

Queues a repaint of the specified rect of the control

This is only useful when the control is visible.

MapPlatformCommand ( string systemCommand, Eto.Forms.Command command ) : void

Specifies a command to execute for a platform-specific command

Some platforms have specific system-defined commands that can be associated with a control. For example, the Mac platform's cut/copy/paste functionality is defined by the system, and if you want to hook into it, you can use this to map it to your own defined logic. The valid values of the systemCommand parameter are defined by each platform, and a list can be retrieved using Control.SupportedPlatformCommands

PointFromScreen ( Eto.Drawing.PointF point ) : Eto.Drawing.PointF

Converts a point from screen space to control space.
PointToScreen ( Eto.Drawing.PointF point ) : Eto.Drawing.PointF

Converts a point from control space to screen space
RectangleFromScreen ( Eto.Drawing.RectangleF rect ) : Eto.Drawing.RectangleF

Converts a rectangle from control space to screen space
RectangleToScreen ( Eto.Drawing.RectangleF rect ) : Eto.Drawing.RectangleF

Converts a rectangle from screen space to control space.
ResumeLayout ( ) : void

Resumes the layout after it has been suspended, and performs a layout

This can be used to optimize some platforms while adding, removing, or changing many child controls at once. Each call to ResumeLayout() must be balanced with a call to SuspendLayout before it.

SuspendLayout ( ) : void

Suspends the layout of child controls

This can be used to optimize some platforms while adding, removing, or changing many child controls at once. It disables the calculation of control positioning until ResumeLayout is called. Each call to SuspendLayout() must be balanced with a call to ResumeLayout.
