Wayland Qt 额外的图片缩放 #1127

TTsdzb · 2024-09-02T12:41:44Z

Summary

Wayland 下，经典用户界面在 Qt 应用程序中会根据系统 DPI 缩放主题背景图片，但其他应用程序不会这么做。这导致使用一些稍复杂的背景图片时，配置好的主题会在 Qt 应用程序中错位。

一般应用程序：

Qt 应用程序（截图区域大小相同）：

Wiki 中提到：

但是Qt是一个例外，由于在Qt下窗口由本地Qt库的API渲染，因此它不支持“由输入法语言渲染文本”选项。

请问我是否应在此处反映该问题？如果不是，请问“本地Qt库”指的是什么？

Steps to Reproduce

设置一个较复杂的图片作为输入面板背景
在其他应用程序中调整边界至合适程度
启动一个 Qt 界面的应用程序并输入，发现图片比其他应用程序更大，导致已配置好的部分元素错位

Expected Behavior

Qt 应用程序的行为与其他应用相同（或者反过来）。

Frontends setup:

The environment variable checked by this script only shows the environment under current shell. It is still possible that you did not set the environment to the whole graphic desktop session. You may inspect the actual environment variable of a certain process by using xargs -0 -L1 /proc/$PID/environ for a certain process that you find not working.

Xim:

${XMODIFIERS}:

Environment variable XMODIFIERS is set to "@im=fcitx" correctly.
Xim Server Name from Environment variable is fcitx.
XIM_SERVERS on root window:

Xim server name is the same with that set in the environment variable.
XIM encoding:

Your LC_CTYPE is set to C whose encoding is not UTF-8. You may have trouble committing strings using XIM.

Qt:

qt4 - ${QT4_IM_MODULE}:

Please set environment variable QT_IM_MODULE to "fcitx" using the tool your distribution provides or add export QT_IM_MODULE=fcitx to your ~/.xprofile. See Input Method Related Environment Variables: QT_IM_MODULE.

qt5 - ${QT_IM_MODULE}:

Please set environment variable QT_IM_MODULE to "fcitx" using the tool your distribution provides or add export QT_IM_MODULE=fcitx to your ~/.xprofile. See Input Method Related Environment Variables: QT_IM_MODULE.

It is OK to use qt5 built-in Wayland im module if your compositor fully supports text-input protocol used by qt5.

Using fcitx5-qt5-immodule-probing to check the actual im module to be used under current environment:
```

Please set environment variable QT_IM_MODULE to "fcitx" using the tool your distribution provides or add export QT_IM_MODULE=fcitx to your ~/.xprofile. See Input Method Related Environment Variables: QT_IM_MODULE.

It is OK to use qt6 built-in Wayland im module if your compositor fully supports text-input protocol used by qt6.

Using fcitx5-qt6-immodule-probing to check the actual im module to be used under current environment:
```

Following error may not be accurate because guessing Qt version from path depends on how your distribution packages Qt. It is not a critical error if you do not use any Qt application with certain version of Qt or you are using text-input support by Qt under Wayland.
Cannot find fcitx5 input method module for Qt4.
