Hi Dmitriy,
Thanks for the quick response - I saw the reply yesterday and wanted to
post the example below last night - but internet connection kept dropping every
few 30 secs for some reason.
Here is the "hello" example that works based on what you suggested.
Kind Regards,
Neil
#include <Wt/WApplication>
#include <Wt/WBreak>
#include <Wt/WContainerWidget>
#include <Wt/WLineEdit>
#include <Wt/WPushButton>
#include <Wt/WText>
#include <Wt/WString>
#include <Wt/WSignalMapper>
using namespace Wt;
class HelloApplication : public WApplication
{
public:
HelloApplication(const WEnvironment& env);
private:
WLineEdit *nameEdit_;
WText *greeting_;
void greetWithData(Wt::WString * data);
};
HelloApplication::HelloApplication(const WEnvironment& env)
: WApplication(env)
{
setTitle("Hello world"); // application title
root()->addWidget(new WText("Your name, please ? ")); // show some text
nameEdit_ = new WLineEdit(root()); // allow text input
nameEdit_->setFocus(); // give focus
WPushButton *b = new WPushButton("Greet me.", root()); // create a button
b->setMargin(5, Left); // add 5 pixels margin
root()->addWidget(new WBreak()); // insert a line break
greeting_ = new WText(root()); // empty text
Wt::WSignalMapper<Wt::WString*> *myMap = new
Wt::WSignalMapper<Wt::WString
*>(this);
myMap->mapped().connect(this, &HelloApplication::greetWithData);
myMap->mapConnect(b->clicked(), new WString(" 1 2 3 4 = some sample
data"));
}
void HelloApplication::greetWithData(Wt::WString * data)
{
greeting_->setText("Hello there, " + nameEdit_->text() +
" here is the data: " + *data);
}
WApplication *createApplication(const WEnvironment& env)
{
return new HelloApplication(env);
}
int main(int argc, char **argv)
{
return WRun(argc, argv, &createApplication);
}
