[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.

Demo helper function to select among default colors. See ShowStyleEditor() for more advanced options. Here we use the simplified Combo() api that pack

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.

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

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

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.

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