// // Fixed.swift // Adwaita // // Created by auto-generation on 26.10.24. // import CAdw import LevenshteinTransformations /// `GtkFixed` places its child widgets at fixed positions and with fixed sizes. /// /// `GtkFixed` performs no automatic layout management. /// /// For most applications, you should not use this container! It keeps /// you from having to learn about the other GTK containers, but it /// results in broken applications. With `GtkFixed`, the following /// things will result in truncated text, overlapping widgets, and /// other display bugs: /// /// - Themes, which may change widget sizes. /// /// - Fonts other than the one you used to write the app will of course /// change the size of widgets containing text; keep in mind that /// users may use a larger font because of difficulty reading the /// default, or they may be using a different OS that provides different fonts. /// /// - Translation of text into other languages changes its size. Also, /// display of non-English text will use a different font in many /// cases. /// /// In addition, `GtkFixed` does not pay attention to text direction and /// thus may produce unwanted results if your app is run under right-to-left /// languages such as Hebrew or Arabic. That is: normally GTK will order /// containers appropriately for the text direction, e.g. to put labels to /// the right of the thing they label when using an RTL language, but it can’t /// do that with `GtkFixed`. So if you need to reorder widgets depending on /// the text direction, you would need to manually detect it and adjust child /// positions accordingly. /// /// Finally, fixed positioning makes it kind of annoying to add/remove /// UI elements, since you have to reposition all the other elements. This /// is a long-term maintenance problem for your application. /// /// If you know none of these things are an issue for your application, /// and prefer the simplicity of `GtkFixed`, by all means use the /// widget.
