Wt

Hello everyone.

I made a simple application who should be used to display various "Page under Construction" informations.

#include <Wt/WEnvironment>
#include <Wt/WApplication>
#include <Wt/WBreak>
#include <Wt/WMenu>
#include <Wt/WStackedWidget>
#include <Wt/WContainerWidget>
#include <Wt/WText>
#include <Wt/WProgressBar>
#include <Wt/WHBoxLayout>
#include <Wt/WVBoxLayout>

// c++0x only, for std::bind
// #include <functional>

using namespace Wt;

/*
 * A simple hello world application class which demonstrates how to react
 * to events, read input, and give feed-back.
 */
class ConstructionApplication : public WApplication {
public:
 ConstructionApplication(const WEnvironment& env);
//Sites
public:
 WWidget* index();
 WWidget* status();
 WWidget* contact();
 void updateTitle();
 WString tr(const char *key);
private:
 WString l_hostname;
 WMenu* l_mainMenu;
 WHBoxLayout *l_mainHBox;
 WVBoxLayout *l_mainVBox;
};

ConstructionApplication::ConstructionApplication(const WEnvironment& env) : WApplication(env) {
l_hostname = env.hostName();
messageResourceBundle().use(appRoot() + "construction", false);

setLocale("");

WStackedWidget *contents = new WStackedWidget();
//WAnimation fade(WAnimation::Fade, WAnimation::Linear, 250);
//contents->setTransitionAnimation(fade);
contents->setId("main_page");

l_mainMenu = new WMenu(contents, Vertical);
l_mainMenu->setRenderAsList(true);
l_mainMenu->addItem(tr("index"), index())->setPathComponent("");
l_mainMenu->addItem(tr("status"), status(), WMenuItem::PreLoading);
l_mainMenu->addItem(tr("contact"), contact(), WMenuItem::PreLoading);
l_mainMenu->itemSelectRendered().connect(this, &ConstructionApplication::updateTitle);

l_mainHBox = new WHBoxLayout(root());
l_mainHBox->setContentsMargins(0, 0, 0, 0);
l_mainVBox = new WVBoxLayout;

l_mainHBox->addWidget(l_mainMenu, 0);
l_mainHBox->addLayout(l_mainVBox, 1);
l_mainVBox->addWidget(contents);
}

void ConstructionApplication::updateTitle() {
if(l_mainMenu->currentItem()) {
 setTitle(l_hostname + " - " + l_mainMenu->currentItem()->text());
}
}

WString ConstructionApplication::tr(const char *key) {
return WString::tr(key);
}

WWidget* ConstructionApplication::index() {
WContainerWidget *result = new WContainerWidget();
result->addWidget(new WText("<h1>Welcome to "+l_hostname+"</h1>"));
result->addWidget(new WBreak());
result->addWidget(new WText("This page is currently under construction."));
return result;
}
WWidget* ConstructionApplication::status() {
WContainerWidget *result = new WContainerWidget();
result->addWidget(new WText("Under contruction."));
return result;
}
WWidget* ConstructionApplication::contact() {
WContainerWidget *result = new WContainerWidget();
result->addWidget(new WText("Under contruction."));
return result;
}

WApplication *createApplication(const WEnvironment& env) {
return new ConstructionApplication(env);
}

int main(int argc, char **argv) {
return WRun(argc, argv, &createApplication);
}

If I visit the site with IE9 I get a blank page most of the time (it works 1 in 10 times). The page works without problems with the latest Firefox. I use nginx as reverse proxy and the wthttpd server backend for delivering the content.

I use nginx 0.7.67-3 (Debian package) and the Wt trunk development version.

If I right click on the page in IE9 I see that the full page was delivered.

Can someone help me with that problem?

Thank you, Louis
