ImGuiWindow is mostly a dumb struct. It merely has a constructor and a few helper methods

Workaround: X11 seems to send spurious Leave/Enter events which would make us lose our position, so we back it up and restore on Leave/Enter (see http

'canvas_selector' is a CSS selector. The event listener is applied to the first element that matches the query. STRING MUST PERSIST FOR THE APPLICATIO

Set to 'true' to enable chaining installed callbacks for all windows (including secondary viewports created by backends or by user. This is 'false' by

GLFW doesn't provide a portable sleep function

Constructors, destructor

Consider using _stricmp/_strnicmp under Windows or strcasecmp/strncasecmp. We don't actually use either ImStricmp/ImStrnicmp in the codebase any more.

- Read about ImTextureID here: https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples - 'uv0' and 'uv1' are texture coordinates.

- ImageButton() adds style.FramePadding*2.0f to provided size. This is in order to facilitate fitting an image in a button. - ImageButton() draws a ba

Note: p_data, p_step, p_step_fast are _pointers_ to a memory address holding the data. For an Input widget, p_step and p_step_fast are optional. Read

As InputText() retain textual data and we currently provide a path for user to not retain it (via local variables) we need some form of hook to reappl

Edit a string of text - buf_size account for the zero-terminator, so a buf_size of 6 can hold "Hello" but not "Hello!". This is so we can easily call

Tip: use ImGui::PushID()/PopID() to push indices or pointers in the ID stack. Then you can keep 'str_id' empty or the same for all your buttons (inste

IMPORTANT: If you are trying to check whether your mouse should be dispatched to Dear ImGui or to your underlying app, you should not use this functio

[WILL OBSOLETE] This was designed for backends, but prefer having backend maintain a mask of held mouse buttons, because upcoming input queue system w

FIXME: This is inlined/duplicated in ItemAdd() FIXME: The id != 0 path is not used by our codebase, may get rid of it?

A triangle is an ear is no other vertex is inside it. We can test reflexes vertices only (see reference algorithm)

Important: this can be useful but it is NOT equivalent to the behavior of e.g.Button()! Most widgets have specific reactions based on mouse-up/down st

== (GetItemID() == GetFocusID() && GetFocusID() != 0)

This is roughly matching the behavior of internal-facing ItemHoverable() - we allow hovering to be true when ActiveId==window->MoveID, so that clickin

Call after a Selectable() or TreeNode() involved in multi-selection. Useful if you need the per-item information before reaching EndMultiSelect(), e.g

This is the only public API until we expose owner_id versions of the API as replacements.

Note that Dear ImGui doesn't know the meaning/semantic of ImGuiKey from 0..511: they are legacy native keycodes. Consider transitioning from 'IsKeyDow
