Code-Example that won't work for me
Added by Quirin Schwanse over 5 years ago
Hey there, tried to write a simple test-application to get familiar with Wt, should actually work but
it seems that I forgot something, can someone just read over this and tell me where I'm wrong? Thank you! _
main.cpp:
[code]
#include "Template.h"
int main(int argc, char *argv[]) {
return Wt::WRun(argc, argv, [](const Wt::WEnvironment &env) {
auto app = std::make_uniqueWt::WApplication(env);
app->messageResourceBundle().use("approot/templates"); //loading templates.xml for messages
app->messageResourceBundle().use("approot/strings_de"); //loading strings_de.xml for messages
app->useStyleSheet("docroot/style.css"); //loading style.css for used stylesheet
app~~root()~~>addNew();
return app;
});
}
[/code]
Template.h:
[code]
#pragma once
#include "Navigation.h"
#include <Wt/WTemplate.h>
class Template : public Wt::WTemplate
{
public:
Template();
};
[/code]
Template.cpp:
[code]
#include "Template.h"
Template::Template() : WTemplate{ tr("tpl.template") }
{
addFunction("tr", &WTemplate::Functions::tr);
auto test = bindWidget("test", std::make_unique());
}
[/code]
Navigation.h:
[code]
#pragma once
#include <Wt/WTemplate.h>
#include <Wt/WApplication.h>
#include <Wt/WLineEdit.h>
#include <Wt/WPushButton.h>
#include <Wt/WText.h>
#include <Wt/WContainerWidget.h>
class Navigation : public Wt::WContainerWidget
{
public:
Navigation(const std::string &name);
private:
std::string name_;
Wt::WPushButton *B_Home;
Wt::WPushButton *B_Discover;
Wt::WPushButton *B_Profile;
};
[/code]
Navigation.cpp:
[code]
#include "Navigation.h"
Navigation::Navigation(const std::string &name) : name_(name)
{
setContentAlignment(Wt::AlignmentFlag::Right);
B_Home = addWidget(std::make_uniqueWt::WPushButton(tr("str.home")));
B_Discover = addWidget(std::make_uniqueWt::WPushButton(tr("str.discover")));
B_Profile = addWidget(std::make_uniqueWt::WPushButton(tr("str.profile")));
}
[/code]

<?xml version="1.0" encoding="utf-8"?>
${test}

This is a fairly bad way to ask a question. Be sure to add what you expect to happen and what actually happens for you. Also, let us know how to set things up to run your example. It's nice when the example is in as few files as possible, but this isn't terrible in that regard. Of course...here I am answering though :shrug:
Wrap extended code examples in < pre>< /pre>@ (with no internal space).
In Template.cpp, you attempt to instantiate a Navigation without supplying any parameters to the constructor. After fixing that, and placing the two .xml files in ./approot/, it works for me (screenshot attached).

Hey, thanks for the feedback, I actually thought about the way u mentioned right after I posted
my bad thread, sorry for that!
Actually makes a lot of sense, since I had the standard constructor implemented without instantiating the Objects, so
just stupid me :<
Thank you! Works for me now with your Solution :>
