# tui/tooltip Show a tooltip on the far right of the workspace bar (the bottom taskbar). The same slot also displays hover help for panel title-bar elements — the right-side buttons show "minimise" / "maximise" / "restore" / "close", the panel-name area shows "panel menu", an open panel-name palette's items show "show config" / "edit source" / "pop out to window" / "app help", and hovering a panel's title icon shows the app name and source path. Hover help takes precedence over the app-set text for as long as the hover lasts. Pass an empty string to clear. ## Syntax

[tui/tooltip "some tooltip text"]
[tui/tooltip ""]    # clear

## Examples

# Contextual help from an on-hover handler
def on-hover {|ev|
    [tui/tooltip "Click to open; Shift+Click to open in a new panel"]
}

# Clear when the pointer leaves
def on-hover-end {|ev|
    [tui/tooltip ""]
}

## Returns nil
