@AfterCompose
public void initSetup(@ContextParam(ContextType.VIEW) Component view) {
Themes.setTheme(Executions.getCurrent(), Infrastructure.getUserLogin().getTheme());
Executions.sendRedirect(null);
final HashMap<String, Object> map = new HashMap<String, Object>();
Selectors.wireComponents(view, this, false);
/* get an instance of the searched CENTER layout area */
Center c1 = borderLayout.getCenter();
/* clear the center child */
c1.getChildren().clear();
map.put("centerArea", c1);
/* Load the left navigation menu for patient cases */
Executions.createComponents("userList.zul", c1, map);
}
But it becomes infinite loop. Because sendredirect again calling the same page. What is the alternate method to do this
You can try to change
Themes.setTheme(Executions.getCurrent(), Infrastructure.getUserLogin().getTheme());
Executions.sendRedirect(null);
to
String theme = Executions.getCurrent(), Infrastructure.getUserLogin().getTheme();
if (!theme.equals(Themes.getCurrentTheme())) {
Themes.setTheme(Executions.getCurrent(), Infrastructure.getUserLogin().getTheme());
Executions.sendRedirect(null);
}
then it should work
Thanks. I will try. But sendredirect flickering the screen. You can the demo here
Senthilchettyin ( 2013-04-29 06:17:10 +0800 )editYes, because the page is reloaded after it is loaded, as a workaround you can try two ways: 1, Make root component invisible (visible="false") and make it visible after the theme is correct. 2. Redirect to a page contains nothing for adjust theme then redirect to the page you want to show.
benbai ( 2013-04-29 11:03:12 +0800 )editThank you very benbai. Now i controlled the flickering problem as you said.
Just done the following to avoid such flickering.
Then from index.zul, i redirected to main.zul which is actual main file for the application.
The ZUL File
<zk> <window apply="org.zkoss.bind.BindComposer" viewmodel="@id('vm')@init('zkexample.zkoss.IndexVM')"> </window> </zk>
The Java Code
import org.zkoss.bind.annotation.AfterCompose; import org.zkoss.bind.annotation.ContextParam; import org.zkoss.bind.annotation.ContextType; import org.zkoss.zk.ui.Component; import org.zkoss.zk.ui.Executions; import org.zkoss.zul.theme.Themes;
public class IndexVM {
@AfterCompose
public void initSetup(@ContextParam(ContextType.VIEW) Component view) {
String theme = FHSessionUtil.getCurrentUser().getTheme();
if (!theme.equals(Themes.getCurrentTheme())) {
Themes.setTheme(Executions.getCurrent(), FHSessionUtil
.getCurrentUser().getTheme());
}
Executions.sendRedirect("main.zul");
}
}
