下面列出了怎么用org.eclipse.jface.text.IWidgetTokenKeeper的API类实例代码及写法，或者点击链接到github查看源代码。
public boolean requestWidgetToken(IWidgetTokenKeeper requester) {
if (PlatformUI.getWorkbench().getHelpSystem().isContextHelpDisplayed())
return false;
return super.requestWidgetToken(requester);
}
public boolean requestWidgetToken(IWidgetTokenKeeper requester, int priority) {
if (PlatformUI.getWorkbench().getHelpSystem().isContextHelpDisplayed())
return false;
return super.requestWidgetToken(requester, priority);
}
@Override
public boolean requestWidgetToken(IWidgetTokenKeeper requester) {
if (PlatformUI.getWorkbench().getHelpSystem().isContextHelpDisplayed())
return false;
return super.requestWidgetToken(requester);
}
@Override
public boolean requestWidgetToken(IWidgetTokenKeeper requester, int priority) {
if (PlatformUI.getWorkbench().getHelpSystem().isContextHelpDisplayed())
return false;
return super.requestWidgetToken(requester, priority);
}
public boolean requestWidgetToken(IWidgetTokenKeeper requester) {
return viewer.requestWidgetToken(requester);
}
public boolean requestWidgetToken(IWidgetTokenKeeper requester, int priority) {
return viewer.requestWidgetToken(requester, priority);
}
public void releaseWidgetToken(IWidgetTokenKeeper tokenKeeper) {
viewer.releaseWidgetToken(tokenKeeper);
}
