Hi Serban,
Although the two methods look similar, they are called under
different circumstances. The initializeFrom inside the performance
tab is inherited the parent class, AbstractLaunchConfigurationTab
and it gets called when the tab is activated. When the Performance
tab is selected (activated), we attempt to rebuild it from the
launch configuration IF a tool was previously selected and saved
as part of the launch configuration. This restores the tab.
handleUpdate is called when a tool is selected within the tab from
the tool selection box. Since the tools are storing their values
in the launchConfiguration, when a new tool is selected we are
tearing down part of the tab and rebuilding it.
To set initial values for widgets, you should only need to put
default values in the tool's xml file. You can set defaults by
creating attributes and associating it with a particular widget.
The TAU tool is a good example of how to set initial values so if
you are trying to develop a tool I would look at the tau tool
plugins. I'm not sure under what circumstances you are seeing an
error window popup twice, but can you provide more details on what
you are trying to do so I can better understand what might be
happening?
Thanks,
Chris

Hello;
I have a question about the PerformanceAnalysisTab
class in PTP, more specifically about the handleUpdate
method.
The method is fairly simple:
private
void
handleUpdate() {
launchTabParent.initializeFrom(this.launchConfiguration);
for
(IJAXBLaunchConfigurationTab tabControl : tabControllers)
{
for
(IUpdateModel m : tabControl.getLocalWidgets().values()) {
m.initialize(this.launchConfiguration,
vmap, launchTabParent.getVariableMap());
}
((JAXBDynamicLaunchConfigurationTab)
tabControl).initializeFrom(this.launchConfiguration);
}
}
The question I have is why do I
need
to initialize all the widget values before calling initializeFrom,
when that method initializes them again?
public
RMLaunchValidation initializeFrom(ILaunchConfiguration
configuration) {
listenerConfiguration
= configuration;
try
{
IUpdateHandler
handler = getParent().getUpdateHandler();
viewers.clear();
for
(Map.Entry<Object, IUpdateModel> e : localWidgets.entrySet())
{
Object key = e.getKey();
if
(key instanceof
Viewer) {
Viewer
viewer = (Viewer) key;
viewers.add(viewer);
}
handler.addUpdateModelEntry(key, e.getValue());
}
LCVariableMap
lcMap = parentTab.getVariableMap();
IVariableMap
rmMap = fControl.getEnvironment();
for
(IUpdateModel m : localWidgets.values())
{
m.initialize(configuration, rmMap, lcMap);
<--- initialized again
}
Do I need to explicitly
initialize the
widget values before calling initializeFrom? The problem I have
is that
the initialization may pop up some error windows and I get them
twice.
