I was not talking about those very purpose-specific widgets. I know they aren't standard components. I'm also not talking about theme- or OS-specific differences. I'm talking about the fact that few of the examples maintained a 100% consistent look and feel
within their own theme. These are not nitpicky things. Maintaining visual consistency between applications is key to achieving usability. Here are some examples:
All of the buttons are non-standard, but the gridview headers and tab controls are standard: https://www.wxwidgets.org/about/screenshots/cars-hotsurf-msw...
Non-standard toolbar buttons, repositioner handles, and rendering and location for tool-window close boxes: https://www.wxwidgets.org/about/screenshots/audacity-msw.png
Skinned background and non-standard grouping panels, but standard buttons, menus, textboxes, etc: https://www.wxwidgets.org/about/screenshots/boinc.jpg
Non-standard coloring on buttons in toolbar: https://www.wxwidgets.org/about/screenshots/ginkgo-windows.j...
Link-buttons used for commands ("Run Benchmark") and reskinned, giganto elements mixed with standard, tiny elements: https://www.wxwidgets.org/about/screenshots/sysmark2012.jpg
An MDI hacked together out of grouping panels: https://www.wxwidgets.org/about/screenshots/trident-msw.jpg
There was absolutely no reason to reskin these buttons and textboxes. Skeuomorphism is bad design: https://www.wxwidgets.org/about/screenshots/audio-evolution-...
A hacked together Ribbon view out of a tab-view placed in the toolbar location, but they also include a separate toolbar section. Finally, that "calculate" button should follow its config elements, not precede them: https://www.wxwidgets.org/about/screenshots/coppercube-msw.j...
