References are only valid until a new value is added to the storage. Calling a Set***() function or a Get***Ref() function invalidates the pointer.

[Internal] Do not use directly

owner_id may be None/Any, but routing_id needs to be always be set, so we default to GetCurrentFocusScope().

FIXME-TABLE: This prevents us from using ImGuiListClipper _inside_ a table cell. The problem we have is that without a Begin/End scheme for rows using

This is called/shared by both the stb_truetype and the FreeType builder.

Sanitize format - Zero terminate so extra characters after format (e.g. "%f123") don't confuse atof/atoi - stb_sprintf.h supports several new modifier

- For scanning we need to remove all width and precision fields and flags "%+3.7f" -> "%f". BUT don't strip types like "%I64d" which includes digits.

Extract the format out of a format string with leading or trailing decorations fmt = "blah blah" -> return fmt fmt = "%.3f" -> return fmt fmt =

Trim str by offsetting contents when there's leading data + writing a \0 at the trailing position. We use this in situation where the cost is negligib

Find end-of-line. Return pointer will point to either first \n, either str_end.

4 bytes-per-pixel

API is designed this way to avoid exposing the 4K page size e.g. use with IsGlyphRangeUnused(0, 255)

Helper for ColorPicker4()

Save current stack sizes for later compare

Scrolling happens only in the central section (leading/trailing sections are not scrolling)

Clear and initialize empty settings instance

Adjust flags: default width mode + stretch columns are not allowed when auto extending

Helpers for internal use

Try to merge two last draw commands

traverse the layout to locate the nearest character to a display position

API click: on mouse down, move the cursor to the clicked location, and reset the selection

discard the oldest entry in the undo list

API drag: on mouse drag, move the cursor and selection endpoint to the clicked location

find the x/y location of a character, and remember info about the previous row in case we get a move-up event (for page up, we'll have to rescan)

stb_textedit internally allows for a single undo record to do addition and deletion, but somehow, calling the stb_textedit_paste() function creates tw

canoncialize the selection so start <= end

find minimum y position if it starts at x1

rects array must be big enough to accommodate all characters in the given ranges

check if a utf8 string contains a prefix which is the utf16 string; if so return length of matching utf8 string
