  • error information is passed to above page as URL parameters
  • retry page at a configurable rate

Custom Dialogs

The browser utilizes custom dialogs, including login prompts, due to the limitations in Qt's default dialog handling. This approach is essential when prompt input is required via a virtual keyboard, as it ensures the keyboard remains interactable and properly targetable.

On a development machine

• install Qt dependencies
• mkdir build
• cd build
• cmake ../
• make
