增加此简单的go gui应用程序的默认字体大小 [英] Increasing default font size of this simple go gui application

问题描述

我正在使用以下简单的演示代码使用 Fyne 程序包创建GUI:

package main
import (
    "fyne.io/fyne/widget"
    "fyne.io/fyne/app"
)
func main() {
    app := app.New()
    w := app.NewWindow("Hello")
    w.SetContent(widget.NewVBox(
        widget.NewLabel("Hello Fyne!"),
        widget.NewButton("Quit", func() {
            app.Quit()
        }),
    ))
    w.ShowAndRun()
}

它可以正常工作，但我想增加此GUI的默认字体大小(以便应在标签，按钮和可能添加到其中的其他小部件(如条目)中增加字体大小).

我看到有一个 theme 对象(使用TextSize()函数)，但我无法使用它来增加字体大小.在type Driver interface中也有一个RenderedTextSize(string, int, TextStyle) Size.

如何在此简单的GUI应用程序中增加默认字体?感谢您的帮助.

解决方案

您可以在主题内使用TextSize()-您需要提供一个自定义主题，该主题是使用myApp.Settings().SetTheme()设置的.

但是，如果您只是希望使用更大的应用程序进行自己的设置，则应尝试将环境变量FYNE_SCALE设置为2.0之类的东西，这将扩展整个用户界面.这会更改计算机的大小，而在主题中设置TextSize会为每个人更改.

值得注意的是，这并不是琐碎的"，因为Fyne小部件故意没有提供太多自定义功能.

I am using following simple demo code to create a GUI using Fyne package:

package main
import (
    "fyne.io/fyne/widget"
    "fyne.io/fyne/app"
)
func main() {
    app := app.New()
    w := app.NewWindow("Hello")
    w.SetContent(widget.NewVBox(
        widget.NewLabel("Hello Fyne!"),
        widget.NewButton("Quit", func() {
            app.Quit()
        }),
    ))
    w.ShowAndRun()
}

It works all right but I want to increase size default font of this GUI (so that font size should increase in label, button and any other widget like entry that may be added to it).

I see there is theme object (with a TextSize() function) that can possibly be used but I am not able to use it to increase font size. There is a also RenderedTextSize(string, int, TextStyle) Size in type Driver interface.

How can I increase default font in this simple GUI application? Thanks for your help.

解决方案

You can use TextSize() within theme - you would need to provide a custom theme as set it with myApp.Settings().SetTheme().

If, however, you just wish a larger application for your own setup then you should try setting the environment variable FYNE_SCALE to something like 2.0 which will scale the whole user interface. This changes the size for your computer whereas setting the TextSize in a theme would change it for everyone.

It’s worth noting that this is not "trivial" because Fyne widgets intentionally do not offer much customisation.
