[DEBUG] List fonts in a font atlas and display its texture

Demo helper function to select among loaded fonts. Here we use the regular BeginCombo()/EndCombo() api which is the more flexible one.

Shrink excess width from a set of item, by removing width from the larger items first. Set items Width to -1.0f to disable shrinking this item.

This function is merely here to free heap allocations.

For 32-bit and larger types, slider bounds are limited to half the natural type range. So e.g. an integer Slider between INT_MAX-10 and INT_MAX will f

Note: p_data, p_min and p_max are _pointers_ to a memory address holding the data. For a slider, they are all required. Read code of e.g. SliderFloat(

Add multiple sliders on 1 line for compact edition of multiple components

Small buttons fits within text without additional vertical spacing.

Using 'hover_visibility_delay' allows us to hide the highlight and mouse cursor for a short time, which can be convenient to reduce visual noise.

This is not 100% symetric with StartMouseMovingWindow(). We do NOT clear ActiveID, because: - It would lead to rather confusing recursive code paths.

Portable helpers

Those light colors are better suited with a thicker font than the default one + FrameBorder

Dockable windows uses Name/ID in the global namespace. Non-dockable items use the ID stack.

Called on manual closure attempt

Order = visible order, not submission order! (which is tab->BeginOrder)

This is called only once a frame before by the first call to ItemTab() The reason we're not calling it in BeginTabBar() is to leave a chance to the us

Remove TabBar data (currently only used by TestEngine)

The *TabId fields are already set by the docking system _before_ the actual TabItem was created, so we clear them regardless.

Note: we may scroll to tab that are not selected! e.g. using keyboard arrow keys

Render text label (with custom clipping) + Unsaved Document marker + Close Button logic We tend to lock style.FramePadding for a given tab-bar, hence

Unlike TableHeadersRow() it is not expected that you can reimplement or customize this with custom widgets. FIXME: No hit-testing/button on the angled

Apply queued resizing/reordering/hiding requests

[Internal] Called by TableSetColumnIndex()/TableNextColumn() This is called very frequently, so we need to be mindful of unnecessary overhead. FIXME-T

For reference, the average total _allocation count_ for a table is: + 0 (for ImGuiTable instance, we are pooling allocations in g.Tables[]) + 1 (for t

Maximum column content width given current layout. Use column->MinX so this value differs on a per-column basis.

FIXME-TABLE: This is a mess, need to redesign how we render borders (as some are also done in TableEndRow)

Output context menu into current window (generally a popup) FIXME-TABLE: Ideally this should be writable by the user. Full programmatic access to that

Fix sort direction if currently set on a value which is unavailable (e.g. activating NoSortAscending/NoSortDescending)

Compact and remove unused settings data (currently only used by TestEngine)

Free up/compact internal Table buffers for when it gets unused

Get settings for a given table, NULL if none

Return the cell rectangle based on currently known height. - Important: we generally don't know our row height until the end of the row, so Max.y will

We allow querying for an extra column in order to poll the IsHovered state of the right-most section

Return the resizing ID for the right-side of the given column.

Note this is meant to be stored in column->WidthAuto, please generally use the WidthAuto field

Return -1 when table is not hovered. return columns_count if hovering the unused space at the right of the right-most visible column.

Return -1 when table is not hovered. Return maxrow+1 if in table but below last submitted row. IMPORTANT* Unlike TableGetHoveredColumn(), this has a o
