- each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer.
|
||||
- if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index your buffer. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
|
||||
- refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade!
|

- removed the 'thickness' parameter from ImDrawList::AddLine().
|

- 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete).
|
||||
- 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount.
|
||||
- 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence

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

- plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID)
