Detailed Description

Convenience class with a label and progress meter.

Synopsis

A QProgressPanel is a convenience class that provides a common functionality: displaying a progress meter along with a label. QProgressPanel also has two optional buttons: a "Hide" button and a "Close" button - pressing either of these buttons sends a signal. Important: it is the responsibility of the caller/parent to handle these signals.

Member Function Documentation

void casa::QProgressPanel::cancel ( )

privateslot

Slot to handle the "Cancel" button's clicked() signal.

Emits the cancelRequested() signal.

void casa::QProgressPanel::cancelRequested ( )

signal

The cancelRequested signal is emitted whenever the "Cancel" button is clicked.

If the QProgressPanel was created without the cancel button, this signal is never emitted.

QLabel* casa::QProgressPanel::getLabel

(

)

Returns the label (QLabel).

QProgressBar* casa::QProgressPanel::getProgressBar

(

)

Returns the progress meter (QProgressBar).

void casa::QProgressPanel::hide ( )

privateslot

Slot to handle the "Hide" button's clicked() signal.

Emits the hideRequested() signal.

void casa::QProgressPanel::hideRequested ( )

signal

The hideRequested signal is emitted whenever the "Hide" button is clicked.

If the QProgressPanel was created without the hide button, this signal is never emitted.

void casa::QProgressPanel::setLabel

(

casacore::String

newLabel

)

Sets the text of the label to the given String.

void casa::QProgressPanel::setValue ( int  value )

slot

Sets the value of the progress meter to the given value.

Note that the progress meter is on a scale of 0 - 100. Also, due to some weirdness with Qt's GUI thread system, calling setValue actually emits a signal which is caught by the progress meter rather than setting the value directly.

void casa::QProgressPanel::updateValue ( int  value )

signal

This is the signal used by setValue() to get around Qt's GUI thread issues.
