how to wrap on and off Text Widget

I don't know is this a best way .

simply rebuild text widget.
keep text and selection.
----
public void createPartControl(Composite parent) {

textArea = new Text(parent,SWT.MULTI|SWT.V_SCROLL|SWT.H_SCROLL);

}

public void setWrap(boolean bool){
Composite parent=textArea.getParent();
String text=textArea.getText();
Point pt=textArea.getSelection();
textArea.dispose();
int style=SWT.H_SCROLL;
if(bool){
style=SWT.WRAP;
}
textArea = new Text(parent,SWT.MULTI|SWT.V_SCROLL|style);
textArea.setText(text);
textArea.setSelection(pt);

parent.layout();

akj speechtools

today i upload my eclipse rcp speech tools.
http://sourceforge.jp/projects/akjrcp/files/?release_id=13713#13713

this is simply wrapped freetts & mbrola.

try it!

create account in sourceforge.jp

If it was possible i'd like to create project at sourceforge.net.

how to change your eclipse rcp application's title and icon

if you hurry anyway,you can do that.

public class OptipngWrapperWorkbenchAdvisor extends WorkbenchAdvisor{

public void postWindowOpen(IWorkbenchWindowConfigurer configurer) {
configurer.setTitle(Messages.getString("optipng_title"));
Image logoImage=ImageDescriptor.createFromURL(OptipngWrapperPlugin.getDefault().find(new Path("icons/akj_eclipse.png"))).createImage(); //$NON-NLS-1$
configurer.getWindow().getShell().setImage(logoImage);
}

}

but this approach has problem. selected icon isn't deliverd to other shell (Help or Updates)
that's not so important thing.

but I recomend you use product extension point.
more detail see
http://eclipse.org/articles/Article-Branding/branding-your-application.html
<extension
id="product"
point="org.eclipse.core.runtime.products">
<product name="akJ Speech Tools"
application="org.jpn.xucker.rcp.speech.SpeechApplication"
>
<property name="windowImage" value="icons/akj.png"/>
</product>
</extension>

How to IAction Disable or Enable

when you something action.you hope disable other action.
at first i didn't found them. finally i found that.
I don't know ,is that right?
but i use that code.
you call this method from view,or change 'this'.
on id-String .use Action ID.
private void setEnabled(boolean bool,String id){
IContributionItem ic=this.getViewSite().getActionBars().getToolBarManager().find(id);
if(ic!=null && ic instanceof ActionContributionItem){
IAction iaction=((ActionContributionItem)ic).getAction();
iaction.setEnabled(bool);
}
}

Open Editor on Eclipse RCP

see that samples.
http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/platform-text-home/development/rcp/examples/index.html

that's difficult.
even in open text files,i should create some classes.
and now I'dont know how to use other editor plugin.
when i open file.
it coused that error
org.eclipse.ui.PartInitException: Text editor does not have a document provider

maybe on 3.1,that become more easy.

give up handle moving view.

on Eclipse 3.01 Windows XP

I don't know how to handle movable views,and
I give up using them.

I choose 2 rules.
Rule 1.Never use folder.
Rule 2.Use setFixed(true) when use setEditorAreaVisible(false)

why folder is movable.
and folder can't back window.

when use setEditorAreaVisible(false) and all views go out,
view didn't come back alone.
maybe everyuser panic that.

Today I try to add preferences my application.
that is something easy.

if you wish use preferences. call that.

PreferenceManager m=PlatformUI.getWorkbench().getPreferenceManager();

PreferenceDialog dialog=new PreferenceDialog(window.getShell(),m);

dialog.open();

off course you should create preference extentions(org.eclipse.ui.preferencePages).

try Eclipse UpdateManager

Today I try to implement UpdateManager.
I see the Update Sites of Eclipse Help.
and I create Feature Project and Update Site Project.
I confused version and other,but finnlay I succede.

but there are problem.if i use UpdateManagerUI.openInstaller(),
include too many other plugins. and my application became really fat size.

so i'd like to release my application as zip archive files.

how to get plugin dir on Eclipse RCP?

finally i choose that aproach.i don't that is best way.

public File toPluginDir(Plugin plugin){
return new File(Platform.getInstallLocation().getURL().getPath(),
"plugins/"
+plugin.getBundle().getSymbolicName()
+"_"
+plugin.getBundle().getHeaders().get("Bundle-Version"));
}

it's too difficult for me handle the Bundle Class.
it's sample of bundle.getHeaders() values.

Bundle-ClassPath='rcp_optipngwrapper.jar'
Bundle-Name='akJ OptipngWrapper Plug-in'
Bundle-Version='1.0.2'
Bundle-Localization='plugin'
Generated-from='1110021669453;type=2'
Bundle-SymbolicName='org.jpn.xucker.rcp.optipngwrapper; singleton=true'
Require-Bundle='org.jpn.xucker.commons,
org.eclipse.ui,
org.eclipse.core.runtime'
Bundle-Activator='org.jpn.xucker.rcp.optipngwrapper.OptipngWrapperPlugin'
Eclipse-AutoStart='true'
Bundle-Vendor='www.xucker.jpn.org'
Manifest-Version='1.0'
Provide-Package='org.jpn.xucker.rcp.optipngwrapper,
