Method Detail

getAppearance

public ProgressBarCell.ProgressBarAppearance getAppearance()

Returns the progress bar appearance.

Returns:

the appearance

getIncrement

public int getIncrement()

Returns the bar's increment value.

Returns:

the increment the increment

render

public void render(Cell.Context context,
          Double value,
          SafeHtmlBuilder sb)

Specified by:

render in interface Cell<Double>

Specified by:

render in class AbstractCell<Double>

reset

public void reset(Cell.Context context,
         XElement parent)

Resets the progress bar value to 0 and text to empty string.

setIncrement

public void setIncrement(int increment)

The number of progress update segments to display within the progress bar (defaults to 10). If the bar reaches the end and is still updating, it will automatically wrap back to the beginning.

Parameters:

increment - the new increment

updateProgress

public void updateProgress(Cell.Context context,
                  XElement parent,
                  double value,
                  String text)

Updates the progress bar value, and optionally its text. If the text argument is not specified, any existing text value will be unchanged. To blank out existing text, pass "". Note that even if the progress bar value exceeds 1, it will never automatically reset -- you are responsible for determining when the progress is complete and calling reset(com.google.gwt.cell.client.Cell.Context, com.sencha.gxt.core.client.dom.XElement) to clear and/or hide the control.

Parameters:

value - A value between 0 and 1 (e.g., .5, defaults to 0)

text - The string to display in the progress text element or null.

updateText

public void updateText(XElement parent,
              String text)

Updates the progress bar text. If specified, textEl will be updated, otherwise the progress bar itself will display the updated text.

Parameters:

text - The string to display in the progress text element
