Hi Larry Excellent work, thank you! The freeze/thaw tool will be a great addition to the label tool bar.
I wonder if the tool could also be active if x/y is data defined and rotation not (currently, x/y/rotation need to be data defined to use the tool).
On a detail level, in QgsMapToolFreezeLabels::highlightLabel you could probably use QgsMapRenderer::mapToLayerCoordinates to transform the rectangle (instead of mCoordTransform ).

Hi, The current large-format project I'm working on requires me to layout, for print, thousands of labels. So I spent the last couple of days making two new tools for the advanced labeling toolbar that allow the user to interactively 'freeze' (write coords and rotation info to attribute table) and 'thaw' (revert from data-defined to dynamic) any rendered labels. *Show Frozen Labels* This tool highlights frozen labels for all visible layers. Blue highlighted labels are frozen, green are frozen and editable (parent layer's in edit mode). *Freeze/Thaw Labels* This tool allows the user to interactively choose, by single or marquee selection, labels to freeze or thaw. The in-memory attribute table is immediately updated and results shown to user. This tool allows the user to interactively manipulate the PAL labeling engine to find the best solutions for their frozen labels. Since the topic and how the tool interacts with the labeling engine is more complicated, I made an intro video. (Note: I haven't had much sleep recently, so it's a bit rough.) http://vimeo.com/dakotacarto/freezethawlabels This is my first C++ project, so I'd be really happy if someone audited the code before I squash the commits and send a pull request: https://github.com/dakcarto/Quantum-GIS/tree/feature_freeze-thaw-labels Only tested on Mac, as of now. Nothing platform-specific about it though.
