A progress bar.
The progress bar can be used to indicate the progress of a certain operation. The text displayed in the progress bar can be customized by specializing text().
To use the progress bar, you need to give it a range (minimum and maximum value), and update the progress using setValue().
WProgressBar is an inline widget.
| const WString& Wt::WProgressBar::format | ( | ) | const |
Returns the progress format string.
| double Wt::WProgressBar::maximum | ( | ) | const |
Returns the maximum value.
| double Wt::WProgressBar::minimum | ( | ) | const |
Returns the minimum value.
| Signal& Wt::WProgressBar::progressCompleted | ( | ) |
A signal that indicates when 100% is reached.
This signal is emitted when setValue(maximum()) is called.
Resizes the widget.
Specifies a fixed size for this widget, setting CSS width and height properties. By default a widget has automatic width and height, which sets a size for the widget following CSS rules.
When the widget is not managed by a layout manager, the automatic (natural) size of a widget depends on whether they widget is a block or inline widget:
When inserted in a layout manager, the size set will be used as a widget's preferred size, but the widget may be given a different size by the layout manager based on available space and stretch factors. The actual size given by a layout manager may be retrieved by making the widget "layout size aware", using setLayoutSizeAware(). If you have defined a "wtResize()" JavaScript method for the widget, then this method will also be called.
The default width and height of a widget is WLength::Auto.
Reimplemented from Wt::WWebWidget.
