hi, all
I have test the WKeyEvent for some hotkey development on the based of
wt-2.1.4, but some unfortunate errors happened, the test case a TableView
application in a WContainerWidget, which can react to the keyPressed.
Error1: The Application can't recognize the modifiers except Shift, maybe Wt
only accept the explicitly entered character?
Error2: In this test case, the application will not get the key pressed out
the range of TableView(not including the ToolBar)
-----test case----------
#include <iostream>
#include <boost/lexical_cast.hpp>
#include <WApplication>
#include <WContainerWidget>
#include <WText>
#include <WEvent>
#include <WStandardItemModel>

#include <Ext/ToolBar>
#include <Ext/Button>
using namespace Wt;
class Test : public WApplication {
public:

void hotKey(WKeyEvent key);
private:

};
Test::Test(const WEnvironment& env)
: button(),
WApplication(env) {
WContainerWidget *ex = new WContainerWidget(root());
ex->resize(WLength(1000), WLength(500));
Ext::TableView *tv = new Ext::TableView(ex);

WStandardItemModel *model = new WStandardItemModel(2, 2, this);
model->setHeaderData(0, boost::any(WString("test")));
