findWidgetByType {RGtk2} | R Documentation

## Find widget in hierarchy by type

### Description

DEPRECATED!! (compatibility wrappers for RGtk 1!)

This function recursively descends the widget hierarchy identified by the root node `win` and finds the first widget that matches the specified target type.

### Usage

    findWidgetByType(win, gtkType = "GtkMenuBar", verbose = FALSE)

### Arguments

`win` | the root node of the widget hierarchy whose children and descendants are to be searced.
`gtkType` | the name of the Gtk type we are looking for. If this is a function, it is called for each widget in the hierarchy until it returns `TRUE`. Each call is given the widget as its only argument and expected to return a logical value indicating whether the widget matches or not. One can use a closure and always return `FALSE` if one wants to iterate over all the widgets and collect the matching ones.
`verbose` | a logical value indicating whether to print information to the console as we recurse.

### Value

The widget that matched or `NULL`.
