Helper to display a little (?) mark which shows a tooltip when hovered. In your own code you may want to display an actual icon if you are using a mer

Unnamed namespace, since we only use this here.

p_min = upper-left, p_max = lower-right Note we don't render 1 pixels sized rectangles properly.

This is one of the very rare legacy case where we use ImGuiWindow methods, it should ideally be flattened at some point but it's been used a lots by w

Buf is zero-terminated, so end() will point on the zero-terminator

Helpers: Bit manipulation

Similar to resize(0) on ImVector: empty string but don't free buffer.

make the selection/cursor state valid if client altered the string

Zero-terminated string hash, with support for ### to reset back to seed value We support a syntax of "label###id" where only "###id" is included in th

Make the UI compact because there are so many fields

the edge passed in here does not cross the vertical line at x or the vertical line at x+1 (i.e. it has already been clipped to those)

Apply requests coming from BeginMultiSelect() and EndMultiSelect(). - Enable 'Demo->Tools->Debug Log->Selection' to see selection requests as they hap

@OPTIMIZE: binary search

Generally for non-user facing functions: assert on invalid ID.

0: East, 3: South, 6: West, 9: North, 12: East

update selection and cursor to match each other

Find glyph, load if necessary, return fallback if missing

Find beginning-of-line

Avoid naming collision with imgui_demo.cpp's HelpMarker() for unity builds.

std::lower_bound but without the bullshit

Push a clipping rectangle for both ImGui logic (hit-testing etc.) and low-level ImDrawList rendering. - When using this function it is sane to ensure

Known size hash It is ok to call ImHashData on a string with known length but the ### operator won't be supported. FIXME-OPT: Replace with e.g. FNV1a

Call IncludeItemByIndex() or IncludeItemsByIndex() *BEFORE* first call to Step() if you need a range of items to not be clipped, regardless of their v

Inputs FIXME: Eventually we should aim to move e.g. IsActiveIdUsingKey() into IsKeyXXX functions.
