从Qt资源文件加载ico时出现问题 [英] Issue when loading an ico from a Qt resource file

问题描述

我使用Qt Designer 4.8.4，我在QMainWindow资源文件中包括两个文件：.ico文件和.gif文件。从代码加载时：

  QPixmap p; 
 p.load（：/ MyApp / media / logo.gif）; // does work 
 p.load（：/ MyApp / media / logo.ico）; //不工作
  

gif文件工作，但不是ico文件。 有任何原因吗？我正在使用ico文件作为窗口图标，并且在运行应用程序时不显示。

，因为 GIF文件正在工作，所以我已成功编译qrc文件。

干杯，

默认情况下，Qt支持以下格式：

格式说明Qt的支持

BMP Windows位图读/写

GIF图像交换格式（可选）阅读

JPG联合图像专家组读/写

JPEG联合图像专家组读取/写入

PNG便携式网络图形读/写

PBM便携式位图读取

PGM便携式Graymap读取

PPM便携式Pixmap读取/写入

TIFF标记的图像文件格式读/写

XBM X11位图读/写

XPM X11 Pixmap读/

I am using Qt Designer 4.8.4 and I include two files in the QMainWindow resource file: a .ico file and a .gif file. When loading from code using:

QPixmap p;
p.load(":/MyApp/media/logo.gif");  // does work
p.load(":/MyApp/media/logo.ico");  // does not work

The gif file works, but not the ico file. Is there any reason? I am using the ico file as the window icon and it is not showing when running the application.

And, YES, I am successfully compiling the qrc file since the GIF file is working.

Cheers,

解决方案

*.ico is not supported.

By default, Qt supports the following formats:

Format Description Qt's support

BMP Windows Bitmap Read/write

GIF Graphic Interchange Format (optional) Read

JPG Joint Photographic Experts Group Read/write

JPEG Joint Photographic Experts Group Read/write

PNG Portable Network Graphics Read/write

PBM Portable Bitmap Read

PGM Portable Graymap Read

PPM Portable Pixmap Read/write

TIFF Tagged Image File Format Read/write

XBM X11 Bitmap Read/write

XPM X11 Pixmap Read/write
