Tracking issue for missing Makepad features

[kevinaboos]

This is a list of features/bugs in Makepad that should be considered blockers for publishing a "good-quality"/sleek application with a good UX.

• TextInput: internal multi-line scrolling, for when the text content does not fit into the size bounds of the TextInput.
• TextInput: single-line mode with left/right panning that follows the cursor.
• TextInput: fix paste behavior to ensure all characters get pasted, not just the first one.
  • A known problem on Android & iOS, not sure about other platforms.
• Windows IME box in the wrong location (it always appears in the upper-left corner, not right above/below the target TextInput): ime issue on windows makepad/makepad#756
• Android IME support, to unlock the full keyboard with autocomplete/autocorrect.
  • cc usage/integration of android-view
• Mobile: touches not registering in many cases, primarily in dynamic views like modals/PageFlip/pop-up panes.
• Ability to instantly re-position/re-size something after drawing it.
  • For ensuring tooltips are properly positioned, context menus don't spill out of the window, etc.
  • Rik said this was possible, but I wasn't able to find any existing examples of it being done.
• Ability to animate panels that slide in/out of the bottom of a view.
  • See Robrix's EditingPane, which uses this margin: {top: 1000} hack to fake it.
  • SlidePanel doesn't work because it assumes the entire app window, not a single parent view, and also doesn't support bottom-edge sliding.
• SVG rendering is broken on Windows, and Linux to a lesser extent. Works well on macOS.
  • resvg-based SVG pipeline has been added, but it isn't yet utilized in any actual Makepad widgets yet (e.g., Icon, Button), so this fix isn't technically available to us yet.
• PortalList: smooth_scroll_to() is inconsistent and doesn't always scroll to the proper position in which the target item is fully in-view.
• PortalList: at_end() is broken and frequently returns false when it actually is at the end, even upon an action that auto-scrolls to the very end.
• Scroll*View: enable finger-based drag scrolling for touch screens: Pending Merge Add touch-based drag scrolling to ScrollBar makepad/makepad#799
• Dock: allow drag-and-drop on all platforms, including mobile (needed for larger Android/iPad devices). Support drag-n-drop on Linux makepad/makepad#650
• Dock/Tabs: allow moving/dragging tabs using fingers, triggered by a long press (for which I've already added native support).
• Dock: enable finger-based drag scrolling through the tab list, and scrolling through the tab list using horizontal scroll gestures (e.g., on a trackpad).
  • Currently only vertical scrolling is supported, which makes sense for a mouse scroll wheel but is confusing for trackpads.
• Dock: when a tab is selected programmatically, automatically scroll the Tabs list to ensure that the selected widget's tab header is visible.
• Text Wrapping: support Ellipsis again.
• Text Wrapping: don't wrap whitespace(s) to the beginning of a new line. It looks strange.
  • example: look at " capabilities" at the start of the second line in this screenshot:
• Text Wrapping: don't insert a soft break before punctuation like . ; , etc. A punctuation mark shouldn't wrap to a new line by itself.
• TextFlow: support vertical alignment of custom widgets w.r.t. the surrounding text: HTML subwidgets cannot be vertically aligned with surrounding HTML text makepad/makepad#712
• Scrolling: allow a vertically-centered view to be vertically scrolled (and vice versa too, with horizontal view too).
