/* This snippet demonstrates a function that will open a Yes/No dialog in MODO using dialog service.
 * 
 * To create a dialog we need dialog service. We use dialog service to allocate message object
 * that will determine the type of dialog that we will open and will contain the text of the message
 * that we want to display. The text needs to be set in the message table in a config file.
 * Next we set message object to our message passing message table name and message key
 * and we use SetCode() method to set the type of a dialog that we want to open.
 * Finally, we open such prepared message via dialog service
 * and translate the result into boolean value.

You return LXfTMOD_DRAW_PIXEL from your ToolModel::Flags method.
Then you'll be called for drawing into screen space.
If you support multiple drawing modes; 3D and screen space,
you can test in your Draw callback by calling ILxView::Flags,
and testing the return type for LXiVIEWv_PIXEL.
You can query the StrokeDraw object passed to your draw method for an ILxView.
When you're in your drawing call, you can call ILxView::Dimensions to get the size of the viewport
to calculate the position to draw.
