Also a general cleanup of CMakeLists.txt and many small code changes to satisfy Clang that complained quite a lot and actually wouldn't compile the binary at all at first.
CMAKE_INSTALL_PREFIX and CMAKE_INSTALL_DATAROOTDIR are now used to resolve the resource path. As of this commit, there are only two paths where resources are searched, under the user home directory and under this install prefix directory (which defaults to /usr/local/share/emulationstation/resources but can be set to for instance /opt/share/emulationstation/resources using the appropriate CMake flags).
This fix 2 bugs with the horizontal scrolling grid :
- The grid is now positioned correctly (bug introduced by the buffer of the dynamic image loader)
- The right column contain the partial tile in horizontal mod, not the bottom row
- This changes make sure the buildTiles function is called only one time, at the end of the applyTheme function.
- The buildTiles function now call calcGridDimension as both are linked to the same events
Add default game image and folder image to the grid. They can be configured by the theme with the gameImage and folderImage properties of the imagegrid.
- Separated private methods and attributes in 3 groups :
- images & entries
- tiles
- miscellaneous
- Renamed some methods :
- buildImages -> buildTiles
- updateImages -> updateTiles
- Moved private methods implementation so they respect the same order as their declaration
- Changed some methods internal variable names and other smalls clean
- Add the GridTileComponent which hold the image and its background
- Add base theming syntax for the ImageGrid and GridTIle
- Numerous refactoring/cleaning in ImageGridComponent
- Add the metadata from the detailed view to the grid view (minus the image, as it doesn't make sens in the grid view)
- Add a callback to the ImageGridComponent to update the metadata info panel when cursor changed
- Grid tile number of columns and rows is now controlled by the grid size, mMargin and mTileMaxSize
- Add a variable mSelectedTileMaxSize to control the size of the selected tile
- Update the render function to display the selected tile on top of the other
