Window: Added ImGuiWindowFlags_NoBackground flag for consistency and to ease creating new flag combinations. Added ImGuiWindowFlags_NoDecoration helper flag which is essentially NoTitleBar+NoResize+NoScrollbar+NoCollapse. (#1660)

|
||||
- Window: Resizing from edges (with io.ConfigResizeWindowsFromEdges Beta flag) extends the hit region
|
||||
of root floating windows outside the window, making it easier to resize windows. Resize grips are also
|
||||
extended accordingly so there are no discontinuity when hovering between borders and corners. (#1495, #822)
|
||||
- Window: Added ImGuiWindowFlags_NoBackground flag to avoid rendering window background. This is mostly to allow
|
||||
the creation of new flag combinations, as we could already use SetNextWindowBgAlpha(0.0f). (#1660) [@biojppm, @ocornut]
|
||||
- Window: Added ImGuiWindowFlags_NoDecoration helper flag which is essentially NoTitleBar+NoResize+NoScrollbar+NoCollapse.
|
||||
- Window, Inputs: Fixed resizing from edges when io.MousePos is not pixel-rounded by rounding mouse position input. (#2110)
|
||||
- BeginChild(): Fixed BeginChild(const char*, ...) variation erroneously not applying the ID stack
|
||||
to the provided string to uniquely identify the child window. This was undoing an intentional change
