    • getRenderPriority

      protected int getRenderPriority()
      Description copied from class: Tool
      Return the render priority for this tool. Tools with higher dispatch priorities are rendered earlier than tools with lower priorities. The priority should be in the range Tool.MIN_PRIORITY...Tool.MAX_PRIORITY. The default priority is equal to Tool.DEFAULT_PRIORITY.
      Overrides:
      getRenderPriority in class Tool
      Returns:
      the dispatch priority

    • setEnabled

      protected void setEnabled(boolean enabled)
      Description copied from class: Tool
      Receive notification from the tool manager about the tool's enabled state. In general, tools need not and should not try to implement different behaviour depending on the enabled state, as this is already covered by the ToolManager calling the Tool.handleEditEvent(boolean, EditEvent) and Tool.render(RenderParameters, boolean) in the appropriate state only. However, some tools may need to perform extended actions (for example, for resource management purposes) upon a change of the enabled state.
      Overrides:
      setEnabled in class Tool
      Parameters:
      enabled - controls whether to enable or disable this Tool

    • render

      render in class Tool
      Parameters:
      parameters - the view component which is currently being rendered
      isActive - whether the called tool is currently active

    • getFrozenStateMode

      public int getFrozenStateMode()

      The frozen state mode describes how instances of the CrossHairPane class handle the frozen mode. See also FROZEN_STATE_DISABLED, FROZEN_STATE_ENABLED, FROZEN_STATE_RESET_ON_DOCCHANGE, FROZEN_STATE_RESET_ON_PAGECHANGE.

      Returns:
      The frozen state mode used by instances of this class.

      Gets the frozen state.
      Returns:
      true if the pane is in frozen state; false otherwise

    • setFrozen

      public void setFrozen(boolean frozen)
