TODO

features

• about view
• prevent duplicate vouchers
• update GPS manually

layout/style

• restyle the header
• idk, new colours?
• move 'about' button somewhere.. logical
• move entry-block button (edit,trash) to the 'tab'
• move entry buttons (add,edit,export,trash) to the floating circle button
• short press to toggle an image, long press to preview

fixes

• fix editing sets (is it only 'name' ?)
• fix camera image orientation on saved files?
• I think the gps position doesn't update properly (fix needs testing)
• exporting on Android is borked

housework

• separate entry types into separate files
• the image preview slides side-to-side when opening
• many docs/comments
• onTextChanged in EntryField and TemplateField is kinda dodgey
  • could Qt.binding() fix it?

future

• more field types
  • range (from, to)
  • combobox (list of options)
• public repo of templates
• map view

Development

• Install Qt 5.14.2+

• Install Java 8

• Install Android Studio

• Use the Android Studio SDK Manager:

  • Install NDK v20+ (v29.0.3)
  • Install SDK v21+ (v29)

Android

• Configure QtCreator:
  • Update to 4.11.1+
  • Set Paths: Tools -> Options -> Devices -> Android
  • https://doc.qt.io/qtcreator/creator-developing-android.html#specifying-android-device-settings

Notes

• Deploying android for release (signed & compiled) is broken in QtCreator 4.11, fixed in 4.11.1
• Can't figure out how to free-self-sign iOS builds. Still, it would only last 7 days before it deletes itself.

iOS

• Buy a Mac
• Install XCode (11+, requires Catalina)
• Configure QtCreator
• Connect an iOS device
• Pay for dev subscription
