Debugging Techniques - Slint 1.3.2 Reference
ADVANCED TOPICS 高级的主题--
On this page we share different techniques and tools we’ve built into Slint that help you track down different issues you may be running into, during the design and development.
在这个页面上,我们分享了我们在Slint中内置的不同技术和工具,这些技术和工具可以帮助您跟踪在设计和开发过程中可能遇到的不同问题。
Use the debug() function to print the values of properties to stderr.
使用debug()函数将属性的值打印到stderr 标准错误。
Animations in the user interface need to be carefully designed to have the correct duration and changes in element positioning or size need to follow an easing curve.
用户界面中的动画需要精心设计,以确保其具有正确的持续时间,元素位置或大小的变化需要遵循缓和曲线。
To inspect the animations in your application, set the SLINT_SLOW_ANIMATIONS
environment variable before running the program. This variable accepts an unsigned integer value that is the factor by which to globally slow down the steps of all animations, automatically. This means that you don’t have to make any manual changes to the .slint
markup and recompile. For example,SLINT_SLOW_ANIMATIONS=4
slows down animations by a factor of four.
要检查应用程序中的动画,请在运行程序之前设置SLINT_SLOW_ANIMATIONS环境变量。该变量接受一个无符号整数值,该数值是全局自动减慢所有动画步骤的因子。这意味着您不必对.slint标记进行任何手动更改并重新编译。例如,SLINT_SLOW_ANIMATIONS=4将动画的速度降低到原来的四倍。
The use of logical pixel lengths throughout .slint
files lets Slint compute the number of physical pixels, dynamically, depending on the device-pixel ratio of the screen. To get an impression of how the individual elements look like when rendered on a screen with a different device-pixel ratio, set the SLINT_SCALE_FACTOR
environment variable before running the program. This variable accepts a floating pointer number that is used to convert logical pixel lengths to physical pixel lengths. For example, SLINT_SCALE_FACTOR=2
renders the user interface in a way where every logical pixel has twice the width and height.
通过在. Slint文件中使用逻辑像素长度,Slint可以根据屏幕的设备像素比动态地计算物理像素的数量。要了解单个元素在具有不同设备像素比的屏幕上呈现时的样子,请在运行程序之前设置SLINT_SCALE_FACTOR环境变量。该变量接受一个浮点指针数,用于将逻辑像素长度转换为物理像素长度。例如,SLINT_SCALE_FACTOR=2以一种方式呈现用户界面,其中每个逻辑像素具有两倍的宽度和高度。
Note: Currently, only the FemtoVG and Skia renderers support this environment variable.
注意:目前,只有FemtoVG和Skia渲染器支持这个环境变量。
Slint attempts to use hardware-acceleration to ensure that rendering the user interface consumes a minimal amount of CPU resources while maintaining smooth animations. However, depending on the complexity of the user interface, quality of the graphics drivers, or the power of the GPU in your system, you may hit limits and experience slowness. To address this issue, set the SLINT_DEBUG_PERFORMANCE
environment variable before running the program, to inspect the frame rate. The following options affect the frame rate inspection and reporting:
Slint尝试使用硬件加速来确保呈现用户界面消耗最少的CPU资源,同时保持平滑的动画。但是,根据用户界面的复杂性、图形驱动程序的质量或系统中GPU的功率,您可能会遇到限制并经历缓慢。要解决这个问题,可以在运行程序之前设置SLINT_DEBUG_PERFORMANCE环境变量,以检查帧速率。以下选项影响帧率检查和报告:
refresh_lazy
: The frame rate is measured only when an actual frame is rendered, for example due to a running animation, user interaction, or some other state change that results in a visual difference in the user interface. If there is no change, a low frame rate is reported. Use this option to verify that no unnecessary repainting happens when there are no visual changes. For example, in a user interface that shows a text input field with a cursor that blinks once per second, the reported frame rate should be two. refresh_lazy:帧率仅在呈现实际帧时测量,例如由于正在运行的动画、用户交互或其他一些导致用户界面视觉差异的状态变化。如果没有变化,则报告低帧率。使用此选项可验证在没有视觉更改时不会发生不必要的重新绘制。例如,在显示文本输入字段的用户界面中,光标每秒闪烁一次,报告的帧率应该是2。
refresh_full_speed
: The user interface is continuously refreshed, even if nothing is changed. This continuous refresh results in a higher load on the system. Use this option to identify any bottlenecks that prevent you from achieving smooth animations. Also disables partial rendering with the software renderer. refresh_full_speed:持续刷新用户界面,即使没有更改。这种持续刷新会导致系统负载增加。使用此选项可以识别任何阻碍实现平滑动画的瓶颈。还禁止使用软件渲染器进行部分渲染。
console
: The frame rate is printed to stderr
on the console. console:将帧速率打印到控制台上。
overlay
: The frame rate is as an overlay text label on top of the user interface in each window. 叠加:帧率作为每个窗口中用户界面顶部的叠加文本标签。
Use these options in combination, separated by a comma. You must select a combination of one frame rate measurement method and a reporting method. For example, SLINT_DEBUG_PERFORMANCE=refresh_full_speed,overlay
repeatedly re-renders the entire user interface in each window and prints the achieved frame rate in the top-left corner. In comparison, SLINT_DEBUG_PERFORMANCE=refresh_lazy,console,overlay
measures the frame rate only when something in the user interface changes and the measured value is printed to stderr
as well as rendered as an overlay text label.
组合使用这些选项,以逗号分隔。必须选择一种帧率测量方法和一种上报方法的组合。例如,SLINT_DEBUG_PERFORMANCE=refresh_full_speed,overlay重复地在每个窗口中重新呈现整个用户界面,并在左上角打印实现的帧率。相比之下,SLINT_DEBUG_PERFORMANCE=refresh_lazy,console,overlay仅在用户界面发生变化时测量帧速率,并且测量值被打印到stderr并作为覆盖文本标签呈现。
The environment variable must be set before running the program. If the application runs on a microcontroller without the standard library, the environment variable must be set during compilation.
必须在运行程序之前设置环境变量。如果应用程序在没有标准库的微控制器上运行,则必须在编译期间设置环境变量。

Backends & Renderers 后端和渲染器
Backends & Renderers - Slint 1.3.2 Reference
In Slint, a backend is the module that encapsulates the interaction with the operating system, in particular the windowing sub-system. Multiple backends can be compiled into Slint and one backend is selected for use at run-time on application start-up. You can configure Slint without any built-in backends, and instead develop your own backend by implementing Slint’s platform abstraction and window adapter interfaces.
在Slint中,后端是封装与操作系统(特别是窗口子系统)交互的模块。多个后端可以编译成Slint,并在应用程序启动时选择一个后端用于运行时。您可以在没有任何内置后端的情况下配置Slint,并且可以通过实现Slint的平台抽象和窗口适配器接口来开发自己的后端。
The backend is selected as follows: 后端选择如下:
The developer provides their own backend and sets it programmatically. 开发人员提供他们自己的后端,并通过编程方式进行设置。
Else, the backend is selected by the value of the SLINT_BACKEND
environment variable, if it is set. 否则,如果设置了SLINT_BACKEND环境变量,则通过该变量的值来选择后端。
Else, backends are tried for initialization in the following order: 否则,按以下顺序尝试初始化后端:
qt
winit
linuxkms
The following table provides an overview over the built-in backends. For more information about the backend’s capabilities and their configuration options, see the respective sub-pages.
下表提供了对内置后端的概述。有关后端功能及其配置选项的更多信息,请参阅相应的子页面。
Backend Name 后端名称 |
Description 描述 | Built-in by Default 默认内置 |
---|---|---|
qt | The Qt library is used for windowing system integration, rendering, and native widget styling. Qt库用于窗口系统集成、呈现和本机小部件样式。 |
Yes (if Qt installed) 是(如果安装了Qt) |
winit | The 的winit library is used to interact with the windowing system. winit库用于与窗口系统交互。 |
Yes 是的 |
linuxkms | Linux's KMS/DRI infrastructure is used for rendering. No windowing system or compositor is required. Linux的KMS/DRI基础架构用于渲染。不需要窗口系统或合成器。 |
No 没有 |
A backend is also responsible for selecting a renderer. See the Renderers section for an overview. Override the choice of renderer by adding the name to the SLINT_BACKEND
environment variable, separated by a dash. For example if you want to choose the winit
backend in combination with the software
renderer, set SLINT_BACKEND=winit-software
. Similarly, SLINT_BACKEND=linuxkms-skia
chooses the linuxkms
backend and then instructs the LinuxKMS backend to use Skia for rendering.
后端还负责选择渲染器。有关概述,请参阅Renderers部分。通过将名称添加到SLINT_BACKEND环境变量(用破折号分隔)来覆盖渲染器的选择。例如,如果您希望选择winit后端与软件渲染器相结合,则设置SLINT_BACKEND=winit-software。类似地,SLINT_BACKEND=linuxkms- Skia选择linuxkms后端,然后指示linuxkms后端使用Skia进行呈现。
Slint comes with different renderers that use different techniques and libraries to turn your scene of elements into pixels. Slint picks a renderer backend on your choice of Backend as well as the features you’ve selected at Slint compilation time.
Slint带有不同的渲染器,使用不同的技术和库将元素场景转换为像素。Slint根据您选择的后端以及您在Slint编译时选择的特性来选择渲染器后端。

You may run into compile issues when enabling the Skia renderer. The following sections track issues we’re aware of and how to resolve them.
启用Skia渲染器时,您可能会遇到编译问题。以下部分跟踪我们所知道的问题以及如何解决它们。
Compilation error on Windows with messages about multiple source files and unused linker input Windows上的编译错误,有关于多个源文件和未使用的链接器输入的消息
You may see compile errors that contain this error and warning from clang-cl: 您可能会看到包含此错误的编译错误和clang-cl的警告:
clang-cl: error: cannot specify '/Foobj/src/fonts/fontmgr_win.SkFontMgr_indirect.obj' when compiling multiple source files
clang-cl: warning: Hausmann/.cargo/registry/src/index.crates.io-6f17d22bba15001f/skia-bindings-0.66.0/skia: 'linker' input unused [-Wunused-command-line-argument]
The Skia sources are checked out in a path that’s managed by Cargo, the Rust package manager. The error happens when that path contains spaces. By default that’s in %HOMEPATH%\.cargo
, which contains spaces if the login name contains spaces. To resolve this issue, set the CARGO_HOME
environment variable to a path without spaces, such as c:\cargo_home
. Skia来源在Rust包经理Cargo管理的路径中进行检查。当该路径包含空格时,会发生错误。默认情况下,它位于%HOMEPATH%\.forge中,如果登录名包含空格,则包含空格。要解决此问题,请将CARGO_HOME环境变量设置为不带空格的路径,例如c:\CARGO_HOME。
Compilation error when compiling for ARMv7 with hardware floating-pointer support 编译支持硬件浮点指针的ARMv7时出现编译错误
You may see compiler errors that contain this message: 您可能会看到包含以下消息的编译器错误:
Unable to generate bindings: ClangDiagnostic("/home/runner/work/slint/yocto-sdk/sysroots/cortexa15t2hf-neon-poky-linux-gnueabi/usr/include/gnu/stubs-32.h:7:11: fatal error: 'gnu/stubs-soft.h' file not found\n")
The Skia build invokes clang in multiple occasions and is sensitive to compiler flags that affect the floating point abi (such as -mfloat-abi=hard
), as they affect header file lookups. Skia构建在多个场合调用clang,并且对影响浮点abi的编译器标志(例如-mfloat-abi=hard)很敏感,因为它们会影响头文件查找。
The solve this, set the BINDGEN_EXTRA_CLANG_ARGS
environment variable to contain the same flags that your build environment also passes to the C++ compiler.
要解决这个问题,将BINDGEN_EXTRA_CLANG_ARGS环境变量设置为包含构建环境也传递给c++编译器的相同标志。
For example, if you’re building against a Yocto SDK, then you can find these flags in the OECORE_TUNE_CCARGS
environment variable.
例如,如果您正在针对Yocto SDK进行构建,那么您可以在OECORE_TUNE_CCARGS环境变量中找到这些标志。

Note 注意
This backend is still experimental. The backend has not undergone a great variety of testing on different devices and there are known issues.
这个后端仍然是实验性的。后端还没有在不同的设备上进行大量的测试,并且存在一些已知的问题。
FemtoVG uses OpenGL, and Skia - unless Vulkan is enabled - uses OpenGL, too. Linux’s direct rendering manager (DRM) subsystem is used to configure display outputs. Slint defaults to selecting the first connected display and configures it at either its preferred resolution (if available) or its highest. Set the SLINT_DRM_OUTPUT
environment variable to select a specific display. To get a list of available outputs, set SLINT_DRM_OUTPUT
to list
.
FemtoVG使用OpenGL, Skia(除非Vulkan被启用)也使用OpenGL。Linux的直接呈现管理器(DRM)子系统用于配置显示输出。Slint默认选择第一个连接的显示器,并将其配置为首选分辨率(如果可用)或最高分辨率。设置SLINT_DRM_OUTPUT环境变量以选择特定的显示。要获得可用输出的列表,请将SLINT_DRM_OUTPUT设置为list。
For example, the output may look like this on a laptop with a built-in screen (eDP-1) and an externally connected monitor (DP-3):
例如,在带有内置屏幕(eDP-1)和外部连接显示器(DP-3)的笔记本电脑上,输出可能如下所示:
DRM Output List Requested: eDP-1 (connected: true) DP-1 (connected: false) DP-2 (connected: false) DP-3 (connected: true) DP-4 (connected: false)
Setting SLINT_DRM_OUTPUT
to DP-3
will render on the second monitor.
将SLINT_DRM_OUTPUT设置为DP-3将在第二台显示器上呈现。
When Skia’s Vulkan feature is enabled, Skia will attempt use Vulkan’s KHR Display extension to render directly to a connected screen. Slint defaults to selecting the first connected display and configures it at its highest available resolution and refresh rate. Set the SLINT_VULKAN_DISPLAY
environment variable to select a specific display. To get a list of available outputs, set SLINT_VULKAN_DISPLAY
to list
.
当Skia的Vulkan功能启用时,Skia将尝试使用Vulkan的KHR显示扩展直接渲染到连接的屏幕。Slint默认选择第一个连接的显示器,并将其配置为最高可用分辨率和刷新率。设置SLINT_VULKAN_DISPLAY环境变量以选择特定的显示。要获得可用输出的列表,请将SLINT_VULKAN_DISPLAY设置为list。
For example, the output may look like this on a laptop with a built-in screen (index 0) and an externally connected monitor (index 1):
例如,在具有内置屏幕(索引0)和外部连接显示器(索引1)的笔记本电脑上,输出可能如下所示:
Vulkan Display List Requested: Index: 0 Name: monitor Index: 1 Name: monitor
Setting SLINT_VULKAN_DISPLAY
to 1
will render on the second monitor.
将SLINT_VULKAN_DISPLAY设置为1将在第二台显示器上呈现。
To select a specific resolution and refresh rate (mode), set the SLINT_VULKAN_MODE
variable. Set it to list
to get a list of available modes. For example the output could look like this:
要选择特定的分辨率和刷新率(模式),请设置SLINT_VULKAN_MODE变量。将其设置为list以获取可用模式的列表。例如,输出可能像这样:
Vulkan Mode List Requested: Index: 0 Width: 3840 Height: 2160 Refresh Rate: 60 Index: 1 Width: 3840 Height: 2160 Refresh Rate: 59 Index: 2 Width: 3840 Height: 2160 Refresh Rate: 50 Index: 3 Width: 3840 Height: 2160 Refresh Rate: 30 Index: 4 Width: 3840 Height: 2160 Refresh Rate: 29 Index: 5 Width: 2560 Height: 1440 Refresh Rate: 59 Index: 6 Width: 1920 Height: 1080 Refresh Rate: 60 Index: 7 Width: 1920 Height: 1080 Refresh Rate: 59 Index: 8 Width: 1920 Height: 1080 Refresh Rate: 50 Index: 9 Width: 1680 Height: 1050 Refresh Rate: 59 ...
Set SLINT_VULKAN_MODE
to 6
to select 1920x1080@60.
设置“SLINT_VULKAN_MODE”为6,选择“1920x1080@60”。
By default the keyboard layout and model is assumed to be a US model and layout. Set the following environment variables to configure support for different keyboards:
默认情况下,假定键盘布局和模型为美国模型和布局。设置以下环境变量以配置对不同键盘的支持:
