gtkTreeViewSetTooltipColumn {RGtk2} | R Documentation

## gtkTreeViewSetTooltipColumn

### Description

If you only plan to have simple (text-only) tooltips on full rows, you can use this function to have `GtkTreeView` handle these automatically for you. `column` should be set to the column in `tree.view`'s model containing the tooltip texts, or -1 to disable this feature.

### Usage

    gtkTreeViewSetTooltipColumn(object, column)

### Arguments

``object`` | a `GtkTreeView`
``column`` | an integer, which is a valid column number for `tree.view`'s model

### Details

When enabled, `"has-tooltip"` will be set to `TRUE` and `tree.view` will connect a `"query-tooltip"` signal handler.

Note that the signal handler sets the text with `gtkTooltipSetMarkup`, so &, <, etc have to be escaped in the text. Since 2.12
