Occurs when the mouse pointer moves while within the bounds of an object.

Namespace:   System.Workflow.ComponentModel.Design
Assembly:  System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)

protected virtual bool OnMouseMove(
	MouseEventArgs eventArgs
)

Parameters

eventArgs
Type: System.Windows.Forms.MouseEventArgs

A MouseEventArgs that contains information about the event.

Return Value

Type: System.Boolean

true if the message is handled; otherwise, false.

OnMouseMove occurs when the mouse pointer moves while within the bounds of an object.

The following code example shows how to override the OnMouseMove method to return the scroll position and to return false so that other components in the designer architecture can process the method.

This code example is part of the Basic Designer Hosting SDK Sample from the DesignerShell.cs file. For more information, seeBasic Designer Hosting.

protected override bool OnMouseMove(MouseEventArgs eventArgs)
{
    //Allow other components to process this event by not returning true.
    if (mouseDown)
    {
        workflowView.ScrollPosition = new Point(eventArgs.X, eventArgs.Y);
    }
    return false;
}
