Hi all,
Today I removed all 'old' grid code, and fully enabled the new grid stuff. >From a user perspective this means: ** a new tab in the document properties dialog, solely meant for grids; the former grid/guide tab is now solely for guides. I envision a list of guides there in the future, for easier deletion of guides etc. ** more than one grid can be active at the same time, although i am having trouble in finding a usefull case for this ** multiple views on the same document share the same grids, but the grid can be turned off for each view separately. For example: one could have an overview view without grid enabled. Duplicate that window and zoom in on some detail; then grids can be shown only for that view, and snapping will only happen in those views for which grids are enabled. (sorry i am not able to explain more clearly) ** grid information is now stored in SVG as a child of sodipodi:namedview. Can someone please make an extension that converts an old grid definition to the new format?
From developer perspective:
** implementation of new grids is much easier now; subclassing CanvasGrid and adding an entry in the is enough. Have a peek at how the rectangular grid is implemented (CanvasXYGrid). ** note that there is no longer "the grid", there might be several grids active now!
Future plans (i will not be working on this soon, due to GSoC Live effects!): ** possibility of enabling not all but a selection of grids for a view. Eg. when there are 4 grids defined in the document, only enable grid2 for a certain view. ** new grids! ** better snapping mechanism to enable snapping to intersections of guides&grids and grids&grids.
A side effect of removal of old gridcode: apparantly the origin of the desktop rules used to be set to the origin of the grid. I find this strange: specifying a grid origin of (2,2) would have me think the origin would be at ruler location (2,2) instead of (0,0) as it is in 0.45.1. I have commented the grid-origin correction to the ruler range, because now there is not a single grid anymore to correct it for. Isn't there a control somewhere to define the documents origin? Now the ruler origin is set to (0,0)
Cheers, Johan
