* Bulk replaced tabs with spaces
* Bulk removed trailing whitespace from lines
* Replaced c-style comments with c++-style comments in file banners
* Replace nested namespace definitions with single concise definitions (C++17), this keeps the indentation more manageable
* Cleanup ordering and spacing of include directives
* Bulk renaming of header file extensions from '.h' to '.hpp'.
* Update CODING-STYLE.md
* Update target_compile_features from cxx_std_11 to cxx_std_20.
* Refresh .clang-format file. Still needs a lot of tweaking.
- Made greater use of smart pointers, eliminating many instances of manual memory management
- Do not use pointers at all for many non-polymorphic classes
- Assorted other code cleanup
- Added side pane for product preview and information
- Product selection is done with a separate pushbutton, so that user gets a
chance to preview the complete product information before committing to the
selection
- Supports two view modes: Grid View and List View
- View mode is automatically stored in Settings, so it will default to the
user's prefered mode
- Should address most concerns in #109 and #142
The width is determined at runtime based on the largest page in the
QTabWidget. Without this fix, the side panel would annoyingly change
width as you selected the search tab for the first time -- this was
particularly annoying in the de_DE locale.
