# `wxPreviewControlBar`
[🔗](https://github.com/erlang/otp/blob/master/lib/wx/src/gen/wxPreviewControlBar.erl#L58)

This is the default implementation of the preview control bar, a panel with buttons and a
zoom control.

You can derive a new class from this and override some or all member functions to change
the behaviour and appearance; or you can leave it as it is.

See:
* `m:wxPreviewFrame`

* `m:wxPreviewCanvas`

* `m:wxPrintPreview`

This class is derived, and can use functions, from:

* `m:wxPanel`

* `m:wxWindow`

* `m:wxEvtHandler`

```

Gets the current zoom setting in percent.

# `new`

```elixir
-spec new(Preview, Buttons, Parent) -> wxPreviewControlBar()
             when
                 Preview :: wxPrintPreview:wxPrintPreview(),
                 Buttons :: integer(),
                 Parent :: wxWindow:wxWindow().
```

# `new`

```elixir
-spec new(Preview, Buttons, Parent, [Option]) -> wxPreviewControlBar()
             when
                 Preview :: wxPrintPreview:wxPrintPreview(),
                 Buttons :: integer(),
                 Parent :: wxWindow:wxWindow(),
                 Option ::
                     {pos, {X :: integer(), Y :: integer()}} |
                     {size, {W :: integer(), H :: integer()}} |
                     {style, integer()}.

Constructor.

The `buttons` parameter may be a combination of the following, using the bitwise 'or' operator:

* wxPREVIEW_DEFAULT: Equivalent to a combination of `wxPREVIEW_PREVIOUS`, `wxPREVIEW_NEXT`
and `wxPREVIEW_ZOOM`.

-spec setZoomControl(This, Percent) -> ok when This :: wxPreviewControlBar(), Percent :: integer().
```
