Raw Normal View History

2020-03-31 06:14:52 +03:00
- Done
- Check events only for interested widgets (use focus for keyboard and region for mouse)
- Add handling of disabled widget nodes
- Add handling of custom external actions for widgets
- Do something with return of custom handlers (the exact same thing we do with event handlers)
- Add scroll support
- Add hstack/vstack containers
- Improve input (keyboard) handling
- Implement copy/paste
- Add HiDPI handling
- Handle window resize
- Improve handling of Color (turn to 0.0 to 1.0 instead of 0 to 255? only do it for alpha?)
- Add handling of non visible widget nodes
- Handle widget fixed size
- Add good looking caret to textField
- Add support for onFocus/onBlur
- Maybe we don't need this and we can get by with position in render function?
- Add support for onEnter/onLeave (keep track of previous active widgets)
- We probably need it for drag&drop
- How is the user going to provide state updates?
2020-04-07 07:04:55 +03:00
- We already provide this with the State monad and corresponding lenses
- Improve mouse support/current state of mouse and keyboard for event handling
2020-04-11 23:31:55 +03:00
- Make handleEvent run inside MonadState (required to update user provided lenses) **CANCELLED**
- Add logic that allows widgets to update user state
- Does it make sense to avoid lenses internally, given that we already include the dependency?
2020-03-31 06:14:52 +03:00
- How will long running (i.e., not immediate) user tasks will be handled?
2020-04-28 00:29:28 +03:00
- Using local coordinates for widgets **CANCELLED**
- How do we adjust current displacement?
2020-04-28 01:42:54 +03:00
- Track drawing operations made by a Widget
- Reorganize drawing operations
2020-04-07 07:04:55 +03:00
- Stop, think and design
2020-03-31 06:14:52 +03:00
- How should all of this be organized?
2020-07-14 01:38:51 +03:00
- How should modules be laid out?
2020-05-04 07:33:44 +03:00
- What are good interfaces for the different parts of the system?
2020-03-31 06:14:52 +03:00
- Does it make sense that handleEvent is the only pure function in a widget?
2020-04-28 00:29:28 +03:00
- Based on the previous design, refactor modules
- Current massive refactor
2020-05-31 02:03:45 +03:00
- Replace Tree with Containers' Tree
- Fix issue with event handling (click makes everything disappear)
- Fix focus situation (remove _focusRing and replace with single focus, then use widgetNextFocusable)
2020-05-31 02:03:45 +03:00
- Provide focus to render (needed by textField)
- Check if resize children still makes sense (maybe the widget itself can resize on the corresponding event?)
- Handle SetFocus request
- Check if WidgetState is really needed
2020-07-14 01:38:51 +03:00
- Maybe Data.Dynamic can be used, but currently abandoned
2020-05-31 02:03:45 +03:00
- Rethink Tree.Path import
- Clean up Seq imports
- Where can we use Seq? Does it make sense to use it everywhere? What about Traversable?
- Reorganize Common Types. What do other projects do? They should be simple to import and use
2020-06-08 21:25:52 +03:00
- Create composite widget, allowing isolated event handling and UI creation
2020-06-06 06:19:21 +03:00
- Create application widget, based on composite
2020-05-31 02:03:45 +03:00
- Remove UserTask concept, handle it as WidgetTask
2020-06-06 06:19:21 +03:00
- Support long running tasks that can provide events through a channel
- Add Multiple response support (extra value in EventResponse)
- Try to remove all those Typeable requirements in CompositeWidget
- Removing Monad from Widget/WidgetInstance was good enough
- Some Typeable constraints still needed, but user should not need to do anything
2020-06-15 00:53:04 +03:00
- Provide a way of initializing the application
- Probably taking a simple event that is relayed to appEventsHandler is enough?
- Implement Global keys
- Improve merge process
2020-06-17 22:15:17 +03:00
- Add a way to get path of widget given an id, and provide a method to send a message/event (most likely, a new Request kind)
- Rename EventResult to something more accurate
- Replace resultWidget and friends with non-Maybe versions (update widgets)
2020-06-03 05:23:23 +03:00
- Add _renderLast_ function to Renderer, which delays rendering until the first pass is done
- Futher calls to _renderLast_ should not be ignored (tooltip on dropdown menu?)
- A _handleDelayedRendering_ also needs to be added
- We also need a way of receiving events on _upper_ layers
2020-06-24 06:45:57 +03:00
- All this is needed for dropdowns, but it's also useful for tooltips
2020-06-26 01:56:00 +03:00
- Create Dropdown
2020-04-28 00:29:28 +03:00
- Improve hstack/vstack
- If available space is greater than requested, do not apply resizing logic
2020-04-28 00:29:28 +03:00
- Does a styling engine make sense or doing something similar to Flutter is simpler?
- Does keeping style for some things (fixed width/height) make sense?
- Yes! All these properties are staying
2020-04-28 00:29:28 +03:00
- Could container handle padding and centering?
2020-06-30 01:50:05 +03:00
- No, staying how it is now. It does not disallow having a container, of course
2020-04-28 00:29:28 +03:00
- Implement styling engine. Think why Maybe Double instead of Maybe Dimension (to handle pixels, percent, etc)
- Handle this with a widget that takes care of assigning space
2020-05-31 02:03:45 +03:00
- Improve FixedSize. Consider adding min/max width/height
2020-06-30 01:50:05 +03:00
- Not for the moment
2020-04-28 00:29:28 +03:00
- Improve ergonomics
- https://hackage.haskell.org/package/string-interpolate
2020-04-28 00:29:28 +03:00
- Check if advanced type level features would improve the design
- Check what syntax extensions can be abused to make life easier
- https://limperg.de/ghc-extensions/#basic-patterns
- https://limperg.de/ghc-extensions/#datakinds
- Maybe -> https://typeclasses.com/extensions-intro
2020-04-28 00:29:28 +03:00
- Look for ways that allow both lenses and user events to be used in the same widget
2020-06-06 06:19:21 +03:00
- Most likely through a Default instance
2020-04-28 00:29:28 +03:00
- Related to previous, look for ways to simplify widget setup. Default instance with common values?
- Find way of providing instance config (style, visibility, etc) before providing children (some sort of flip operator)
- Just provide `style` after children. SwiftUI does it this way
2020-07-03 23:22:03 +03:00
- Fix border drawing. Handle simple case (more efficient)
- Fix scroll click navigation
2020-07-03 23:22:03 +03:00
- Highlight bar when mouse over
- Highlight handle when mouse over
- Handle clicks in bar outside handle
- Handle handle drag
- Mouse over on overlapping axis gives precedence to vertical scroll
- Keep sending mouse move event if mouse is away but button is still pressed
- Handle mouse enter/leave window events
2020-07-11 04:08:19 +03:00
- Add support for scroll requests from children
2020-06-26 01:56:00 +03:00
- Improve Dropdown
- Expose customizable interface
- Request scroll when needed
2020-06-28 03:03:06 +03:00

2020-07-12 03:48:26 +03:00
- Check why vstack fails when using [spacer, listView]
2020-07-12 22:53:48 +03:00
- Remove status from Click event. Add ButtonPressed and ButtonReleased events
2020-07-14 01:38:51 +03:00
- Change order of parameters. We should always pass _old_ before _new_
2020-07-08 05:23:13 +03:00
- Unify criteria for instantiation
- Component name without underscore receives parameters positionally
- Component name with underscore receives Config instance
2020-07-15 02:53:31 +03:00
- If two flexible sized and one remaining elements are in a vstack, problems arise
2020-07-14 06:05:35 +03:00
- Add renderer parameter to resize. It will be needed for auto adjustable Label and to handle ellipsis in texts
- Maybe creating a record of functions would be useful?
- Besides calcTextBounds, we need isClipboardPaste and isClipboardCopy which could be customizable
- Customization discarded. What would it be needed for?
2020-06-24 06:45:57 +03:00
- Try to unify path handling on widgetFind and widgetNextFocusable
2020-07-18 22:36:59 +03:00
- This is cancelled fo the moment. I can't find a good reason for doing it.
- WidgetEnv was added as a parameter for completeness sake
- This is also needed for widgetUpdateSizeReq and widgetResize
- Generalize the "startFrom" concept of widgetFind (and also validate it's actually well/fully implemented)
2020-07-19 04:29:48 +03:00
- Should Resize be restored? -> Restored
- Make sure enabled/visible attributes are being used
- This needs modifying WidgetContext (former PathContext) to include visible and enabled attributes
- Move widgetPath into WidgetInstance (do it in init/merge)
- Move currentPath into WidgetInstance
- Move focusedPath and targetPath to WidgetEnv
- Visible and enabled would get updated on init/merge
2020-07-30 07:39:48 +03:00
- Format code!
2020-08-08 02:37:15 +03:00

2020-09-01 02:43:03 +03:00
- DrawStyledBackground should draw borders after widget content
- Request text input when text field gets focus (required for mobile)
- Also set TextInputRect
- Improve textField
- Add text selection/editing to textField
- Find non visible character that returns correct height if input is empty
- Can we generalize widgetFind?
- To find widgetInstances that need a specific kind of event (entities that need timeStep)
- Instead of passing Point, pass WidgetQuery ADT. Currently it would support... PointQuery
- Do we need this?
- It is implemented in chore/unify-query. I honestly don't think it's an improvement
- Further textField improvements
- Handle long text and cursor position
- Scissor needed?
- Add support for changing cursor position with mouse click
2020-08-30 07:19:54 +03:00
- Rethink Image handling
- Should image component keep a copy around?
- Should it be provided to renderer every time and, if removed, put back in the list?
- Otherwise, when graphics memory is exhausted new images will not be added (until the widget is disposed)
- Rethink the idea of global theme in WidgetEnv
- Add option to render inner rounded borders with normal outer ones
2020-09-11 08:13:23 +03:00
- Further textField improvements

2020-09-26 07:44:54 +03:00
- Think widget config in a similar way to style config (combinator functions)
2020-09-22 22:38:48 +03:00
- textField should support textFieldV and validInputV
2020-09-26 23:44:47 +03:00
- Add mandatory event parameter for V constructors
- Why does the model update when trying to input a char in FloatingInput?
- Focus event not received after clicking and gaining focus
- Rethink focus handling. Maybe return a list of all focusable elements? Currently shift-tab is not possible
- Added a direction parameter to widgetFindNextFocus
- Think about argument position for widgets, in particular listview/radio
- Should value come before items/option?
- Should we use a list of configs instead of <> operator?
2020-10-01 05:27:36 +03:00

- Reorganize modules.
- Common and Widget merged into new Core?
- Widget.Widgets moved to Widget?
- WidgetCombinators and StyleCombinators merged into a single Combinators?

- Create separate Util/WidgetUtil (rename Types to WidgetTypes)
- Simplify imports
- Create Lens.hs in each module instead of directory
- Clean up checkbox/radio (fgcolor, etc)
2020-10-05 23:10:08 +03:00
- Simplify Main.hs by abstracting SDL initialization
2020-10-09 23:13:30 +03:00
- Add center, right components based on box
- Validate font exists before using it in NanoVG (crashes otherwise)
- Also added default font
- Check if textBounds is enough, or we're missing descending part of font
- getFullTextSize should be used?
2020-10-09 23:13:30 +03:00
- Make label use fixed height by default
- Do not draw non visible items in grid/stack (outside viewport)
- Apply scissor
2020-10-05 20:11:04 +03:00
- WidgetRequest for error messages? Probably not worth it
- Maybe provide a config where a notification/lens can be sent?
2020-09-25 02:32:59 +03:00
- Fix dropdown issues
2020-10-05 20:11:04 +03:00
- Show listview in appropriate location (if dropdown is at the bottom, the listView should be up)
2020-09-25 02:32:59 +03:00
- Implement OnChange/OnChangeReq for listView and dropdown (currently they only implement the Idx versions)

2020-10-21 07:54:13 +03:00
- Handle findNextFocus in zstack (only consider top layer, unless configured otherwise)
- Keyboard not working on dropdown
- Make sure that focus change requests do not leave overlay if active (most likely an if clause is needed in handleFocusChange)
- Return list of actions instead of Monoid in eventHandler
- Add way of requesting findNextFocus (needed on Dropdown)
- Add way of ignoring unassigned events in stack (or return nothing from findByPoint)
- Update style when merging to avoid recalculating/merging theme every time
- Use theme for all components
- Replace uses of Seq.zip with foldlWithIndex
2020-10-28 20:34:37 +03:00
- Check provided renderArea is used correctly

- Move combinators out of exported Core (but still export from Monomer)
- Cancelled, not sure if it's an improvement
2020-11-06 07:12:59 +03:00
- Maybe unify criteria on zstack? Top layer config for both focus/click?
- Check getState/merge in all components
2020-11-07 04:35:46 +03:00
- Further textField improvements
- Check displaced textField when adding characters on right align
- Also, when right is reached from left, everything is pushed out of screen
- Double clicking on empty puts the cursor at the end of ghost character
- Right aligned version has cusor overlaid (add caret size to offset in specific cases)
- Check clipboard
2020-11-10 02:17:16 +03:00
- Check Container thing in hover adding columns (not targetValid = Nothing should be removed)
- Add missing keyboard functions in Event
- Handle onBlur/onFocus in all focusable widgets
- Find way of avoiding hover effects when widget is not in the top layer
- Hover should only be active for top level item
- I need to think a way of setting a layer state for zstack
2020-11-18 22:37:25 +03:00
- Maybe isPointInViewport should be replaced by something specific for each Widget
- Generalized utility functions to use them in specific widgets
- The findWidgetByPoint route is problematic, since it can lead to mutual recursion
- TextStyle changes **CANCELLED**
- TextOverflow in TextStyle?
- Add Bold/Italic support (instead of different Font for each case)
- Button should change color when clicked/actioned
2020-11-19 05:01:23 +03:00

Maybe postponed after release?
2020-11-20 07:37:35 +03:00
- Avoid excessive delay on window resize
- Check 1px difference on right side of labels/buttons (probably already fixed)
- VStack should set itself to a fixed size if all children are fixed
- ZStack should set _weIsTopLayer based on used space
2020-11-19 05:01:23 +03:00
- Restore focus to previous widget when zstack changes (dialog situation)
- Also think about not losing focus because of click (when onlyTopFocusable is active)
- Further textField improvements
- Handle undo history
- Handle mouse selection
- Create numeric wrapper that allows increasing/decreasing with mouse
- Avoid findNextFocus on unfocusable children (listView items)
2020-11-18 22:37:25 +03:00
- Does this make sense? Check with a composite listView item
- Focus event may need to be handled to update highlighted item
- Create Keystroke component (shortcuts and general key handling like Esc for dialog)
2020-10-21 01:07:51 +03:00
- Create Tooltip component. It just wraps a given component and draws the tooltip with renderOverlay
- Create Theme widget to override global theme
- Image widget could also have a ByteString version
2020-11-18 22:37:25 +03:00
- Compare Cairo/Skia/ImDrawList interfaces to make Renderer able to handle future implementations
2020-10-09 23:13:30 +03:00
- Can _wiChildren be removed from Widget and only be kept in Container?
2020-11-07 04:35:46 +03:00
- Image
- Can performance be improved?
- Does adding function to return imgData from Renderer make sense? Replace imageExists?
- Create Slider
- Create Dial
2020-10-21 01:07:51 +03:00
- Create Split
- Create self rendered version of dropdown and list
2020-04-28 00:29:28 +03:00

- Create Layout with width/heights specified in percents
2020-11-02 02:28:11 +03:00
- Consider https://eugenkiss.github.io/7guis/tasks/
2020-04-28 00:29:28 +03:00
- Drag & drop for user (add attribute indicating if component supports being source/target)
- Add new request types (drag started, drag stopped, drag cancelled)
- Add new events (drag hover)
2020-06-07 04:54:51 +03:00
- SDL supports Drag and Drop integration with OS
2020-11-20 07:37:35 +03:00
- Improve window resize situation
- SDL does not send resize until operation has finished, making content look ugly because it's not updated
- Check SDL_SetEventFilter trick instead of normal polling (https://wiki.libsdl.org/SDL_SetEventFilter)
- Should StyleState be a phantom type?
- A branch was created and got it working
2020-10-14 16:47:18 +03:00
- Getting the types working for meant extending that idea to Widget was logical
- Interfaces got ugly quickly. Need to revisit
- Look for opportunities to reduce code duplication (CompositeWidget and BaseContainer)
2020-11-17 00:04:23 +03:00
- Check threadDelay usage: https://stackoverflow.com/questions/33149324/haskell-ghc-per-thread-memory-costs
- Check if using [lifted-async](https://github.com/maoe/lifted-async) is worth it
2020-11-18 22:37:25 +03:00
- Look for alternatives to NanoVG
- Check ImDrawList. Support for OpenGL/Metal/Vulkan out of the box
- Check SDL_Surface + Cairo backend. It most likely won't happen
- Can we cache some drawing operations?
- Add new request types (drag started, drag stopped, drag cancelled)
- Add new events (drag hover)
- SDL supports Drag and Drop integration with OS
