使用QT Jambi进行截图

发布于 2024-08-28 16:51:50 字数 730 浏览 7 评论 0原文

我正在使用 QT Jambi (java) 来制作浏览器窗口的屏幕截图。我的主要方法像这样启动框架：

QApplication.initialize(new String[1]);

ScreenshotMain widget = new ScreenshotMain();
widget.showFullScreen();
QApplication.exec();

当浏览器完成加载时，将调用以下方法并获取屏幕截图。

public void loadDone() {
// Taking screenshot
QPixmap pixmap;
pixmap = QPixmap.grabWidget(browser);

pixmap.save(writeTo, "png");
System.out.println("Made screenshot "+writeTo);

browser.loadProgress.disconnect(this);
browser.loadFinished.disconnect(this);
QApplication.closeAllWindows();

我

现在的问题如下：

如何在不打开浏览器窗口并加载内容的情况下从应用程序中截取屏幕截图。我的想法是，我有一个服务器应用程序，我不想打开一个窗口来制作屏幕截图。

你们有没有人有这样使用 QT Jambi 进行屏幕截图的经验？

非常感谢您的帮助马克

I am using QT Jambi (java) to make screenshots of a browser window.
My main method starts the framework like this:

QApplication.initialize(new String[1]);

ScreenshotMain widget = new ScreenshotMain();
widget.showFullScreen();
QApplication.exec();

and when the browser is done with the loading the following method is invoked and takes the screenshot.

public void loadDone() {
// Taking screenshot
QPixmap pixmap;
pixmap = QPixmap.grabWidget(browser);

pixmap.save(writeTo, "png");
System.out.println("Made screenshot "+writeTo);

browser.loadProgress.disconnect(this);
browser.loadFinished.disconnect(this);
QApplication.closeAllWindows();

}

My question now is the following:

How can I make screenshots out of an application without having to open a browser window, have it load the content. The idea is that I have a server application and I don´t want to open a window to make the screenshot.

Does anyone of you have experience to make screenshots using QT Jambi in this way.

Thanks a lot for your help
