- make UBDrawingController::mActiveRuler private
- use guarded pointer to avoid dangling pointer dereferencing
- provide public accessor functions
- consider a ruler active only if it is visible
Added checks for the size of the interior, cut-out triangle to make sure
everything is drawn correctly at small sizes; buttons are now also
hidden if they overflow from the tool.
- The background selection palette now includes a slider to change the
size of the background grid. Default min/max values are 16 and 64px,
defined in UBSettings. Grid resizes dynamically as the slider is moved.
- Measuring tools' (ruler, triangle) markers follow grid size: 1 square
of the background grid corresponds to 1cm
- Grid size can be different for each page of a document
- Grid size is saved in the .svg
- Documents with a background grid but no specified grid size follow the
default size defined in UBSettings.
Previously, grid size was calculated based on DPI, which can vary from
one OS, computer or display to the next. This new setting allows
documents to be migrated from one machine to another with no unexpected
changes in grid size happening. It also makes it easy to correct any
problems importing old documents (whose grid size might be smaller or
larger than expected when imported on a new version of OpenBoard).
- Corrected and cleaned up rotation calculation
- Fixed button position/size issues (clickable area didn't correspond to the button image)
- Fixed tool flashing during resizing
- (new feature) Buttons now scale proportionally to the protractor when it is resized
- Everything is now drawn by default at a scale of 1 instead of 1.5
- Pen width set to 0 (i.e always 1 pixel thick regardless of zoom), to keep the old look & feel
- Scaled the marker tool image (.svg) to look like it did before without scaling it in code
- Removed debug messages
Tested on OS X, works fine.
