- image/image button: misalignment on padded/bordered button?
|
||||
- image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that?
|
||||
- image button: not taking an explicit id is odd.
|
||||
- slider/drag: ctrl+click when format doesn't include a % character.. disable? display underlying value in default format? (see InputScalarAsWidgetReplacement)
|
||||
- slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
|
||||
- slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar). (#1946)
|
||||
- slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.

- font: MemoryTTF taking ownership confusing/not obvious, maybe default should be opposite?

- font: storing MinAdvanceX per font would allow us to skip calculating line width (under a threshold of character count) in loops looking for block width

- font/demo: add tools to show glyphs used by a text blob, display U16 value, list missing glyphs.

- font/demo: demonstrate use of ImFontGlyphRangesBuilder.
