Here is my basic implementation of performApply() and updateData(), an index of a combo box get saved in this example..
With this its possible to save preferences depending on selected build configuration (also proper behaviour when switching to other tab and ok/apply button handling).
protected void updateData(ICResourceDescription cfg)
{
ICConfigurationDescription cfg2 = cfg.getConfiguration();
ICStorageElement el;
try
{
el = cfg2.getStorage(F16_BUILD_PREF_ID,false);
if(el == null)
{
_cpuTypeCombo.select(DEFAULT_CPUIndex);
}
else
{
ICStorageElement[] storageChild = el.getChildrenByName("cpuTypeIndex");
_cpuTypeCombo.select(new Integer(storageChild[0].getAttribute("index")));
}
}
catch (CoreException e)
{
e.printStackTrace();
}
}
protected void performApply(ICResourceDescription src,
ICResourceDescription dst)
{
Integer index = _cpuTypeCombo.getSelectionIndex();
ICConfigurationDescription cfg = dst.getConfiguration();
ICConfigurationDescription srcCfg = src.getConfiguration();
ICStorageElement el;
ICStorageElement el2;
try
{
el = cfg.getStorage(F16_BUILD_PREF_ID,false);
el2 = srcCfg.getStorage(F16_BUILD_PREF_ID,false);
if(el == null)
{
el2 = cfg.getStorage(F16_BUILD_PREF_ID,true);
el2 = el2.createChild("cpuTypeIndex");
el2.setAttribute("index",index.toString());
el = cfg.getStorage(F16_BUILD_PREF_ID,true);
el = el.createChild("cpuTypeIndex");
el.setAttribute("index",index.toString());
_comboIndex = index;
}
else
{
ICStorageElement[] storageChild = el.getChildrenByName("cpuTypeIndex");
storageChild[0].setAttribute("index",index.toString());
ICStorageElement[] storageChild2 = el2.getChildrenByName("cpuTypeIndex");
storageChild2[0].setAttribute("index",index.toString());
_comboIndex = index;
}
}
catch (CoreException e)
{
e.printStackTrace();
}
}
Strange thing is to save the data twice in ICResourceDescription src and dst, if not chaning between tabs has incorrect behaviour.
Second not perfect thing is that performOK() has no possibility to save the configuration because of missing ICResourceDescription parameter, so you have to hold your own ICResourceDescription in your class and do the same like in performApply() there....
But its working, thanks guys :)
