[Drawkit] tool to create object of pre-set size then click to place?

[Graham Cox]

Hi Allan,

I think what you've done is fine - I've subclassed DKObjectCreationTool for much the same purpose.

One thing you could do to finesse it, if it makes sense in your app, is to allow the mouse down to add the object as a 'pending' object, then allow it to be dragged and only added to the layer on mouse up. This would allow you to click-drag-release the object to position it exactly where you want it. While an object is 'pending' it can still have its position set as normal to allow dragging into place. A single click still achieves the same result as adding on mouse down.

P.S. A Happy New Year to you and all DK-ers!

It sets the cursor with an image based on the prototype object so that when the tool is clicked the cursor changes to an image of the object that will be "stamped." On a mouse down event the prototype object is added to the target layer. If "sticky tools" are set ( [DKToolController setAutomaticallyRevertsToSelectionTool:NO]) then you can stamp/insert many of the same object over and over again.
