NAME
gtk4-builder-tool - GtkBuilder File Utility
SYNOPSIS
gtk4-builder-tool <COMMAND> [OPTIONS...] <FILE>
gtk4-builder-tool validate <FILE>
gtk4-builder-tool enumerate <FILE>
gtk4-builder-tool simplify [OPTIONS...] <FILE>
gtk4-builder-tool preview [OPTIONS...] <FILE>
gtk4-builder-tool screenshot [OPTIONS...] <FILE>
DESCRIPTION
gtk4-builder-tool can perform various operations on GtkBuilder UI defi-
nition files.
COMMANDS
Validation
The validate command validates the given UI definition file and reports
errors to stderr.
Enumeration
The enumerate command lists all the named objects that are present in
the UI definition file.
Preview
The preview command displays the UI definition file.
This command accepts options to specify the ID of the toplevel object
and a CSS file to use.
--id=ID
The ID of the object to preview. If not specified, gtk4-builder-tool
will choose a suitable object on its own.
--css=FILE
Load style information from the given CSS file.
Screenshot
The screenshot command saves a rendering of the UI definition file as a
png image or node file. The name of the file to write can be specified
as a second FILE argument.
This command accepts options to specify the ID of the toplevel object
and a CSS file to use.
--id=ID
The ID of the object to preview. If not specified, gtk4-builder-tool
will choose a suitable object on its own.
--css=FILE
Load style information from the given CSS file.
--node
Write a serialized node file instead of a png image.
--force
Overwrite an existing file.
Simplification
The simplify command simplifies the UI definition file by removing
properties that are set to their default values and writes the result-
ing XML to the standard output, or back to the input file.
When the --3to4 option is specified, the simplify command interprets
the input as a GTK 3 UI definuition file and attempts to convert it to
GTK 4 equivalents. It performs various conversions, such as renaming
properties, translating child properties to layout properties, rewrit-
ing the setup for GtkNotebook, GtkStack, GtkAssistant or changing
toolbars into boxes.
You should always test the modified UI definition files produced by
gtk4-builder-tool before using them in production.
Note in particular that the conversion done with --3to4 is meant as a
starting point for a port from GTK 3 to GTK 4. It is expected that you
will have to do manual fixups after the initial conversion.
--replace
Write the content back to the UI definition file instead of using
the standard output.
--3to4
Transform a GTK 3 UI definition file to the equivalent GTK 4 defini-
tions.
