- window: autofit feedback loop when user relies on any dynamic layout (window width multiplier, column). maybe just clearly drop manual autofit?
|
||||
- window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list.
|
||||
- window: allow resizing of child windows (possibly given min/max for each axis?)
|
||||
- window: background options for child windows, border option (disable ronuding)
|
||||
- window: resizing from any sides? + mouse cursor directives for app.
|
||||
- widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc.
|
||||
- widgets: clip text? hover clipped text shows it in a tooltip or in-place overlay
|
||||
- main: considering adding EndFrame() - optional, else done in Render(). and Init()
|
||||
- main: add IsItemActive()
|
||||
- main: IsItemHovered() returns true even if mouse is active on another widget (e.g. dragging outside of sliders). Maybe not a sensible default? Add parameter or alternate function?
|
||||
- main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes
|
||||
- main: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode?

- combo: turn child handling code into pop up helper

- list selection, concept of a selectable "block" (that can be multiple widgets)

- menubar, menus
|
||||
- gauge: various forms of gauge/loading bars widgets
|

- color: better color editor.
|
||||
- plot: make it easier for user to draw into the graph (e.g: draw basis, highlight certain points, 2d plots, multiple plots)
|

- plot: "smooth" automatic scale, user give an input 0.0(full user scale) 1.0(full derived from value)
