How to display Google Map Details in another Qt UI

**RajeevSahu** · 2010-08-02, 12:23

Hi Friends,

I am working on a project that will fetch data from the google map and should display the fetched data in another UI window.

Currently, I am able to display the google marker and the respective marked data on QWebView control after a single left mouse click. But I want to redirect these displayed data to another UI Window.

I don't know how to perform this operation. If any body has any idea, please share with me.

Kindly go through the following link to access the whole project I have done so far:

Thanks,
Rajeev

Hi... this is just an update:

I followed Form Extractor Example as a solution to the problem. Here also I am facing some issues.

Please check the example details:

http://doc.qt.nokia.com/4.6/webkit-formextractor.html

As per the above link I tried to build the Form Extractor Project, but I am confused after the Submit button is clicked, because I don't know which "Q_SIGNALS" of "qwebframe.h" is called.:

The example don't have the "form.html" that is required to load, so I developed my own "form.html".

The contents of my modified "form.html" is:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<title>Form Extractor Example</title>
</head>

<body onload="" onunload="" topmargin="0" leftmargin="0">
<div id="map" style="width: 341px; height: 271px"></div>
<form name="myform" >
<div align="center">
<br><br>
First name:
<input name= "firstname" type="text" size="25" value="">
<br>
Last name:
<input name= "lastname" type="text" size="25" value=""><br>
Gender:
<input type="radio" name="group1" value="Male" checked>Male<br/>
<input type="radio" name="group1" value="Female"> Female<br/>
<input name= "check" type="checkbox" size="25" value="" /> Check here if you would like to receive regular updates from us: <br>
<input type=submit value = "Sumbit"/>

</div>
</form>
</body>
</html>

The modified "formextractor.cpp" file is:

#include "formextractor.h"

#include <QWebElement>

FormExtractor::FormExtractor(QWidget *parent, Qt::WFlags flags)
: QWidget(parent, flags)
{
ui.setupUi(this);
ui.webView->setUrl(QUrl("qrc:/form.html"));
connect(ui.webView->page()->mainFrame(), SIGNAL(loadFinished()),this, SLOT(populateJavaScriptWindowObject()));
connect(ui.webView->page()->mainFrame(), SIGNAL(loadFinished()), this, SLOT(submit()));
//connect(ui.webView->page()->mainFrame(), SIGNAL(loadStarted()), this, SLOT(submit()));
//connect(ui.webView->page()->mainFrame(), SIGNAL(initialLayoutCompleted()), this, SLOT(submit()));
//connect(ui.webView->page()->mainFrame(), SIGNAL(provisionalLoad()), this, SLOT(submit()));
//connect(ui.webView->page()->mainFrame(), SIGNAL(javaScriptWindowObjectCleared()), this, SLOT(submit()));
resize(300, 300);
}

FormExtractor::~FormExtractor()
{
}

void FormExtractor::submit()
{
QWebFrame *frame = ui.webView->page()->mainFrame();

QWebElement firstName = frame->findFirstElement("#firstname");
QWebElement lastName = frame->findFirstElement("#lastname");
QWebElement maleGender = frame->findFirstElement("#genderMale");
QWebElement femaleGender = frame->findFirstElement("#genderFemale");
QWebElement updates = frame->findFirstElement("#updates");

ui.firstNameEdit->setText(firstName.evaluateJavaScript("this.value").toString());
ui.lastNameEdit->setText(lastName.evaluateJavaScript("this.value").toString());

if (maleGender.evaluateJavaScript("this.checked").toBool())
ui.genderEdit->setText(maleGender.evaluateJavaScript("this.value").toString());
else if (femaleGender.evaluateJavaScript("this.checked").toBool())
ui.genderEdit->setText(femaleGender.evaluateJavaScript("this.value").toString());

if (updates.evaluateJavaScript("this.checked").toBool())
ui.updatesEdit->setText("Yes");
else
ui.updatesEdit->setText("No");
}

void FormExtractor:

opulateJavaScriptWindowObject()
{
ui.webView->page()->mainFrame()->addToJavaScriptWindowObject("formExtractor", this);
}

By looking this example please figure out the problem!!!

Thanks....
