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
