qwebview

问题 I am using QWebView to render a html page using setHTML method. In the html page body section I am mentioning width and height for the html page, if we are changing the width and hegiht of the QWebView window at run time by calling setGeometry(x,y,w,h), then how to make the html page adjust itself to fit the content fully in streched QWebView window? 回答1: You need to handle window.onresize() event in javascript.

问题 I tried this: QPrintDialog printdia(MyWevView); printdia.exec(); QPrinter* printer = printdia.printer(); QPainter painter(printer); MyWevView->render(&painter, MyWevView->pos(),MyWevView->visibleRegion()); I know I don't check if the user accepts but that's not the problem...everytime, I don't see the dialog, it just prints so first I don't understand why the QPrintDialog doesn't appear and second why it knows my printer and go directly prints the text I guess fixing my first problem will

问题 Now this code works with the slot mechanism. However, I want to try out the signal way also. However, I am unable to do so? Any more ideas on it? I want to call function f1 of the Javascript from the QT. However, I am unable to do so. I don't see the callback being received by the JS f1(). I have followed the earlier post on it, Qt QWEBview JavaScript callback . However, I am unable to do so. Here is my code. #include <QtGui/QApplication> #include <QApplication> #include <QDebug> #include

问题 Here is my situation: I have created a QWebview, loaded a Youtube page, and logged in. I select upload option (http://www.youtube.com/my_videos_upload), and choose a video to upload. However, youtube always returns "The server has returned an invalid response. Please follow these steps and try uploading the file again." How can I solve that problem? Thanks. EDIT: the code I'm using is: import sys from PyQt4.QtCore import QUrl from PyQt4.QtGui import QApplication from PyQt4.QtWebKit import

问题 I created a Qt widget project and added a webEngine or webKit. On webEngine or webKit I set the url to a localhost and loaded the CesiumJS default HelloWorld.html. JUST IT. When I selected "natural earth" as map, the application has trhow a SIGSEGV error (segmentation fault). What in Qt can throw this error? how can i avoid this. Is there any webView configuration (memory limit, Local Storage, etc)? This is my Main.qml import QtQuick 2.5 import QtQuick.Window 2.2 import QtWebEngine 1.1 Window

问题 I would like to load a sort of "web application" in a QWebView . My "web application" is made up of some HTML5 pages with CSS, Javascript and pictures. It is totally autonomous. It does not need a server. I am quite new to Qt programming. Is there a way to embed those files into the Qt project and load them in the QWebView when the program starts? I already managed to load those pages from a remote HTTP server but my application must be standalone. EDIT Thank you for your solution Yodabox.

问题 I have followed the answer by X.Jacobs on this Question, and was trying to create an app that will open multiple windows with different parameters, but it doesn't work, looks, like app is opening windows, but not load the webpage. #! /usr/bin/env python2.7 from PyQt4.QtCore import * from PyQt4.QtGui import* from PyQt4.QtWebKit import * import sys, signal url = 'http://http://forums.fedoraforum.org/showthread.php?t={0}' class Opener(QWebView): def __init__(self, param=None): QWebView.__init__

问题 EDIT 4 All this while I was thinking that it is the markers problem, that they do not get dragged! Now I have realized, that NO mouse click works on the map when it is displayed in Qt widget . The following code, I pasted in an HTML file and opened through Firefox, this worked flawlessly! and the same doesn't respond when I click on the map on QtWidget :rolleyes: Can anyone confirm this for me or tell me what wrong I am doing? Google Maps JavaScript API Example <script type="text/javascript">

问题 How would i go about sizing the QWebView window with the size of the window? Right now i see i can only give it certain dimensions, but how can i make it 100% width and 100% height, and change as i make a window bigger or smaller? Basically if i was to resize, it would resize the QWebview as well. How do i go about this? I see there is size dimensions but i dont see how to have it resize based on the window app. 回答1: Add your QWebView inside a layout. QWebView *webView = new QWebView;

问题 i need to be able to react on focus changes in QWebPage. I used microFocusChanged() signal and it gives me almost desirable behavior, but anyway i don't know how to know which element is selected. I want to do some actions when any editable element on page gets or loses focus.

It may be some dedicated handler object or an existing object like your
