  • Constructor Details

    • ComponentResizer

      public ComponentResizer()
      Convenience contructor. All borders are resizable in increments of a single pixel. Components must be registered separately.

    • ComponentResizer

      public ComponentResizer​(java.awt.Component... components)
      Convenience contructor. All borders are resizable in increments of a single pixel. Components can be registered when the class is created or they can be registered separately afterwards.
      Parameters:
      components - components to be automatically registered

    • ComponentResizer

      public ComponentResizer​(java.awt.Insets dragInsets, java.awt.Component... components)
      Convenience contructor. Eligible borders are resisable in increments of a single pixel. Components can be registered when the class is created or they can be registered separately afterwards.
      Parameters:
      dragInsets - Insets specifying which borders are eligible to be resized.
      components - components to be automatically registered

    • ComponentResizer

      public ComponentResizer​(java.awt.Insets dragInsets, java.awt.Dimension snapSize, java.awt.Component... components)
      Create a ComponentResizer.
      Parameters:
      dragInsets - Insets specifying which borders are eligible to be resized.
      snapSize - Specify the dimension to which the border will snap to when being dragged. Snapping occurs at the halfway mark.
      components - components to be automatically registered

  • Method Details

    • getDragInsets

      public java.awt.Insets getDragInsets()
      Get the drag insets
      Returns:
      the drag insets

    • setDragInsets

      public void setDragInsets​(java.awt.Insets dragInsets)
      Set the drag dragInsets. The insets specify an area where mouseDragged events are recognized from the edge of the border inwards. A value of 0 for any size will imply that the border is not resizable. Otherwise the appropriate drag cursor will appear when the mouse is inside the resizable border area.
      Parameters:
      dragInsets - Insets to control which borders are resizeable.

    • getMaximumSize

      public java.awt.Dimension getMaximumSize()
      Get the components maximum size.
      Returns:
      the maximum size

    • setMaximumSize

      public void setMaximumSize​(java.awt.Dimension maximumSize)
      Specify the maximum size for the component. The component will still be constrained by the size of its parent.
      Parameters:
      maximumSize - the maximum size for a component.

    • getMinimumSize

      public java.awt.Dimension getMinimumSize()
      Get the components minimum size.
      Returns:
      the minimum size

    • setMinimumSize

      public void setMinimumSize​(java.awt.Dimension minimumSize)
      Specify the minimum size for the component. The minimum size is constrained by the drag insets.
      Parameters:
      minimumSize - the minimum size for a component.

    • deregisterComponent

      public void deregisterComponent​(java.awt.Component... components)
      Remove listeners from the specified component
      Parameters:
      components - the component the listeners are removed from

    • registerComponent

      public void registerComponent​(java.awt.Component... components)
      Add the required listeners to the specified component
      Parameters:
      components - the component the listeners are added to

    • registerComponent

      public void registerComponent​(java.lang.String authorizedDirection, java.awt.Component... components)

    • getSnapSize

      public java.awt.Dimension getSnapSize()

      the snap size.

    • setSnapSize

      public void setSnapSize​(java.awt.Dimension snapSize)
      Control how many pixels a border must be dragged before the size of the component is changed. The border will snap to the size once dragging has passed the halfway mark.
      Parameters:
      snapSize - Dimension object allows you to separately spcify a horizontal and vertical snap size.
