- 2015 / 01 / 11 ( 1.30 ) big font / image API change . now loads TTF file . allow for multiple fonts . no need for a PNG loader .
removed GetDefaultFontData ( ) . uses io . Font - > GetTextureData * ( ) API to retrieve uncompressed pixels .
added texture identifier in ImDrawCmd passed to your render function .
removed IO . PixelCenterOffset ( unnecessary , can be handled in user projection matrix )
- 2014 / 12 / 10 ( 1.18 ) removed SetNewWindowDefaultPos ( ) in favor of new generic API SetNextWindowPos ( pos , ImGuiSetCondition_FirstUseEver )
- 2014 / 11 / 28 ( 1.17 ) moved IO . Font * * * options to inside the IO . Font - > structure .
- 2014 / 11 / 26 ( 1.17 ) reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility

If text or lines are blurry when integrating ImGui in your engine :
- in your Render function , try translating your projection matrix by ( 0.5f , 0.5f ) or ( 0.375f , 0.375f )
- try adjusting ImGui : : GetIO ( ) . PixelCenterOffset to 0.5f or 0.375f
If you are confused about the meaning or use of ID in ImGui :
- some widgets requires state to be carried over multiple frames ( most typically ImGui often wants remember what is the " active " widget ) .

- main : IsItemHovered ( ) returns true even if mouse is active on another widget ( e . g . dragging outside of sliders ) . Maybe not a sensible default ? Add parameter or alternate function ?
- main : IsItemHovered ( ) make it more consistent for various type of widgets , widgets with multiple components , etc . also effectively IsHovered ( ) region sometimes differs from hot region , e . g tree nodes
- main : IsItemHovered ( ) info stored in a stack ? so that ' if TreeNode ( ) { Text ; TreePop ; } if IsHovered ' return the hover state of the TreeNode ?
! - drawlist : handling of PixelCenterOffset is badly inconsistent ( sometimes in callee , sometimes in caller ) .
- scrollbar : use relative mouse movement when first - clicking inside of scroll grab box .
- scrollbar : make the grab visible and a minimum size for long scroll regions
! - input number : very large int not reliably supported because of int < > float conversions .
