Occasionally introducing changes that are breaking the API. The breakage are generally minor and easy to fix.
|
||||
Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
|
||||
|
||||
- 2015/07/05 (1.42) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.

- 2015/07/07 (1.42) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.
|
||||
this necessary change will break your rendering function! the fix should be very easy. sorry for that :(
|
||||
- if you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update your copy and you can ignore the rest.
|
||||
- the signature of io.RenderDrawListsFn has changed!

each ImDrawList now contains both a vertex buffer (vtx_buffer) and an index buffer (idx_buffer). For each command, render elem_count/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.
|
||||
- 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
