## ◆ IsAvailable()

bool wxAppProgressIndicator::IsAvailable | ( |  | ) | const

Check if the application progress display is available.

Currently this only returns true when using wxMSW and running under Windows 7 or later systems (which provide task bar button API) or when using wxOSX.

If this method returns false, no other methods of this class do anything, but they may still be called without any ill effects.

Makes the progress bar run in indeterminate mode.

## ◆ SetRange()

void wxAppProgressIndicator::SetRange | ( | int | range | ) |

## ◆ SetValue()

void wxAppProgressIndicator::SetValue | ( | int | value | ) |

Set the progress value in taskbar button of parent window.

Parameters

  value | The new value of the progress meter. It should be less than or equal to the range.
