SYNOPSIS
- kgendesignerplugin [OPTIONS...] file
DESCRIPTION
kgendesignerplugin chooses sensible defaults for most settings, so minimal configuration is usually necessary.
OPTIONS
-o file
- The name for the generated C++ file. If not given, stdout will be used.
-n plugin-name
- Provided for compatibility. The default value for the PluginName option in the input file.
-g group
- Provided for compatibility. The default value for the DefaultGroup option in the input file.
--author
- Show author information.
--license
- Show license information.
-h, --help
- Show a brief help text.
-v , --version
- Show version information.
FILE FORMAT
The input file is an ini-style configuration file (specifically, it is in the format supported by the KConfig framework) that describes a set of widgets. It contains a [Global] section, providing general information about the plugin, and a section for each widget that should be included in the plugin.
The [Global] section can have the following entries:
DefaultGroup
- The default value for the Group entry in the class sections (default: "Custom", unless the -g option is given).
Includes
- A (comma-separated) list of required includes (default: empty). Note that the header files for the widgets specified later in file should not be listed here; instead, this is for special headers for the plugin's own use, like those for classes providing previews.
PluginName
- The name of the main C++ class in the plugin (default: "WidgetsPlugin", unless the -n option is given).
Each class should have its own [ClassName] section, which can include the following entries:
CodeTemplate
- The value returned by the codeTemplate() function of the plugin, which is marked for "future use" by Qt(TM) Designer (default: empty).
ConstructorArgs
-
The arguments to pass to the constructor of the class given by
ImplClass; these must be surrounded by parentheses (default: "(parent)"). The only variable guaranteed to be available is
parent, which is the parent
QWidget
passed by
Qt(TM)
Designer.
This entry is ignored if CreateWidget is set.
CreateWidget
- The code necessary to create an instance of the widget (default: uses new to create an instance of the class given by the ImplClass entry, passing the arguments specified by ConstructorArgs). See the notes for ImplClass and ConstructorArgs.
DomXML
- An XML UI description of the widget (default: the default provided by the Qt(TM) Designer plugin headers).
Group
- The group to display the widget under in Qt(TM) Designer (default: the value of the DefaultGroup entry in the [Global] section).
IconName
- The image file or standard icon name to use as the icon for this widget in the Qt(TM) Designer widget list (default: a PNG file named with the section name, with any double colons removed, in the "pics" directory of a compiled-in resource file; for example, :/pics/Foo.png in the section [Foo], or :/pics/FooBar.png in the section [Foo::Bar]).
ImplClass
-
The class that should be used to create an instance of the widget for the use of
Qt(TM)
Designer (default: the section name). Note that this does not actually have to be the class that would be created for an end application: that is determined by the
DomXML.
This entry is ignored if CreateWidget is set.
IncludeFile
- The header that needs to be included to use this widget (default: the lowercase version of the section name, with any colons removed and ".h" appended; for example, foo.h in the section [Foo], or foobar.h in the section [Foo::Bar]).
IsContainer
- Whether this widget can contain other widgets (default: false).
ToolTip
- The tooltip to display when hovering over the widget in the widget list of Qt(TM) Designer (default: the section name, with " Widget" appended; for example, Foo Widget in the section [Foo]).
WhatsThis
- The What's This text associated with the widget in Qt(TM) Designer (default: the section name, with " Widget" appended; for example, Foo Widget in the section [Foo]).
EXAMPLES
The simplest description file might look like
-
[Foo] ToolTip=Displays foos [Bar] ToolTip=Bar editor
Note that each class must have at least one key set (ToolTip was used in this example), otherwise it will be ignored.
Usually, you want to change at least the user-visible text, which means the ToolTip, WhatsThis and Group entries. Additionally, setting the plugin name can be a good idea to prevent possible symbol clashes and not confuse debuggers (both the debugger application and the person doing the debugging):
-
[Global] PluginName=FooWidgets DefaultGroup=Display [Foo] ToolTip=Displays bears WhatsThis=An image widget that displays dancing bears [Bar] ToolTip=Bar editor WhatsThis=An editor interface for bars for bears Group=Editing
More complex files may be necessary if you have namespaced classes or extra options that need supplying to constructors, for example:
-
[Global] PluginName=FooWidgets DefaultGroup=Foo [Foo::Bar] ToolTip=Displays bars WhatsThis=A widget that displays bars in a particular way IncludeFile=foo/bar.h IconName=:/previews/bar.png [Foo::Baz] IncludeFile=foo/baz.h ConstructorArgs=(Foo::Baz::SomeOption, parent) Group=Foo (Special) IsContainer=true IconName=:/previews/baz.png
Sometimes especially complex widgets might need a special "preview class" implementation for use in Qt(TM) Designer; this might be a subclass of the real widget that just does some extra setup, or it might be a completely different implementation.
-
[Global] Includes=foopreviews.h [FancyWidget] ImplClass=FancyWidgetPreview
