Hi Graeme,
I don't know if what follows is the best way... but when I export a file
on my applications sometimes I want to display a progress bar to give users
some feed back... I have done the following:
public abstract class DefaultExportPanel extends Panel {
/**
*
*/
private static final long serialVersionUID = 1L;
private AbstractExportDialogButton button;
private WebMarkupContainer progress;
/**
* @param id
*/
public DefaultExportPanel(String id, AbstractExportDialogButton button) {
super(id);
this.button = button;
setOutputMarkupId(true);
}
@Override
protected void onBeforeRender() {
if(!this.button.getExportTask().isFinished()) {
for(Object behavior : getBehaviors()) {
if(behavior instanceof AjaxSelfUpdatingTimerBehavior) {
remove((AjaxSelfUpdatingTimerBehavior)behavior);
}
}
add(new AjaxSelfUpdatingTimerBehavior(Duration.seconds(2)));
progress = new ProgressReportPanel("progress",
DefaultExportPanel.this.button.getExportTask().getProgressReporter());
addOrReplace(progress);
} else {
for(Object behavior : getBehaviors()) {
if(behavior instanceof AjaxSelfUpdatingTimerBehavior) {
remove((AjaxSelfUpdatingTimerBehavior)behavior);
}
}
add(new AjaxSelfUpdatingTimerBehavior(Duration.seconds(100)));
progress = new DownLoadExportPanel("progress",
this.button.getExportTask().getFile()) {
private static final long serialVersionUID = 1L;
@Override
public String getContentType() {
return DefaultExportPanel.this.getContentType();
}
@Override
public String getMessage() {
return DefaultExportPanel.this.getDowloadMessage();
}
};
progress.setOutputMarkupId(true);
addOrReplace(progress);
}
super.onBeforeRender();
}
public abstract String getContentType();
public abstract String getDowloadMessage();
}
and the corresponding markup:
<html xmlns:wicket>
<wicket:panel>
<table width="100%" align="center" cellpadding="0" cellspacing="0">
<tr>
<td align="center">
<div wicket:id="progress"></div>
</td>
</tr>
</table>
</wicket:panel>
</html>
The part:
add(new AjaxSelfUpdatingTimerBehavior(Duration.seconds(100)));
progress = new DownLoadExportPanel("progress",
this.button.getExportTask().getFile()) {
private static final long serialVersionUID = 1L;
@Override
public String getContentType() {
return DefaultExportPanel.this.getContentType();
}
@Override
public String getMessage() {
return DefaultExportPanel.this.getDowloadMessage();
}
};
progress.setOutputMarkupId(true);
after removing the behaviors I had to add it because otherwise I would get
an exception when using IE... I know this works, or is working for me with
the snapshot of 1.4.X branch I use, but I'm not sure if its the best way to
achieve this...
Best,
Ernesto
