Re: [udig-devel] default tool example

[Jody Garnett <jody.garnett@xxxxxxxxx>]

Thanks; I was able to fix the enablement of the initial Zoom tool by update the MapEditorWithPalette.

It has a part listener (to determine when the editor has focus and reset the tool manager to pay attention to the editor); I updated this code to set the active tool; and everything went fine from there...

That is *great* so we are half way there ...

 

if you look at the other email about "hooking stuff" up (How to run modal toolbar contributions) I think we can handle the other half of the problem.

 

Can you commit the code to make the correct tool highlighted in the palette

a) our screen snaps will be correct

b) we can tackle registering the correct tool with the map as a separate problem

Thanks for that Jody,

 

Unfortunately root.setDefaultEntry(tool); set’s Zoom as highlighted in the palette, but the tool is still not active so dragging the mouse does not zoom in.

 

I have also tried using a ToolProxy as such:

 

     ToolProxy toolProxy = (ToolProxy) modalItem;

     toolProxy.setActive(true);

 

But that was no help either.

 

At this moment I am still stuck so moving onto another issue and hopefully someone has an idea as to how to get the Zoom tool active as default.

 

Thanks, Scott.

Hi Scott:

 

I am trying to hunt down example(s).

 

There is what I have sorted ...

 

1) ToolManager owns the concept of the default tool ...

    

   ToolManager.defaultModalToolProxy

 

2) this method has package visibility; and is accessed directly (there is no getter!)

   

   Here is an example of MenuToolCategory checking if its new menu item is the default (and thus should start out life selected)

 

  menuItem = new MenuItem(parent, SWT.RADIO, index);

            menuItem.setText(tool.getName());

            menuItem.setImage(tool.getImage());

            if (items.contains( ((ToolManager)manager).defaultModalToolProxy))

                menuItem.setSelection(true);

 

3) there is also a static final ToolProxy.DEFAULT_ID which is how it figures out which thing to use as the defaultModalTool

 

    /**

     * The ID of the default tool: Zoom

     */

    private static final String DEFAULT_ID = "net.refractions.udig.tools.Zoom"; //$NON-NLS-1$

 

4) The ToolPalette has the concept of a default entry; so our MapToolPaletteFactory could perform a similar check to above

    

    So perhaps something like the following will work?

 

                        for( ModalItem modalItem : category ) {

                String label = fixLabel(modalItem.getName());

                ToolEntry tool = new MapToolEntry(label, modalItem, category.getId());

              if( ToolProxy.DEFAULT_ID.equals( tool.getId() ) ){

                     root.setDefaultEntry( tool ); // will this work??

              }

                drawer.add(tool);

        }
