# wxControl(3erl)

Functions for wxControl class

## NAME

wxControl - Functions for wxControl class

## DESCRIPTION

This is the base class for a control or "widget".

A control is generally a small window which processes user input and/or displays one or more item of data.

See: *wxValidator* (not implemented in wx)

This class is derived (and can use functions) from: *wxWindow* *wxEvtHandler*

wxWidgets docs: wxControl

## EVENTS

Event types emitted from this class: *command\_text\_copy*, *command\_text\_cut*, *command\_text\_paste*

## DATA TYPES

```
wxControl() = wx:wx_object()
```

## EXPORTS

```
getLabel(This) -> unicode:charlist()
```

Types:

This = wxControl()\

Returns the control's label, as it was passed to *setLabel/2*.

Note that the returned string may contains mnemonics ("&" characters) if they were passed to the *setLabel/2* function; use *GetLabelText()* (not implemented in wx) if they are undesired.

Also note that the returned string is always the string which was passed to *setLabel/2* but may be different from the string passed to *SetLabelText()* (not implemented in wx) (since this last one escapes mnemonic characters).

```
setLabel(This, Label) -> ok
```

Types:

This = wxControl()\
 Label = unicode:chardata()\

Sets the control's label.

All "&" characters in the *label* are special and indicate that the following character is a *mnemonic* for this control and can be used to activate it from the keyboard (typically by using *Alt* key in combination with it). To insert a literal ampersand character, you need to double it, i.e. use "&&". If this behaviour is undesirable, use *SetLabelText()* (not implemented in wx) instead.
