Fix Qt6 deprecated APIs: QCheckBox::checkStateChanged, ExploratoryLocationViewshed
- Replace QCheckBox::stateChanged with checkStateChanged in: - lts_dialog.cpp - simple_esri_layer.cpp (2 occurrences) - layer_control_widget.cpp - symbol_dialog.cpp - Replace LocationViewshed with ExploratoryLocationViewshed (ArcGIS SDK v300): - viewshed_analysis.h/.cpp - ViewshedLocation.h/.cpp - function_dialog.cpp (include) - Update ViewshedLocation member variable type to ExploratoryLocationViewshed Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

/**
|
||||
@brief **%KTextTemplate::Engine** is the main entry point for creating %KTextTemplate
|
||||
Templates.
|
||||
|
||||
The **%KTextTemplate::Engine** is responsible for configuring and creating Template
|
||||
objects. In typical use, one or more AbstractTemplateLoader objects will be
|
||||
added to the Engine to load template objects, and plugin directories will be
|
||||
set to enable finding template tags and filters.
|
||||
|
||||
@code
|
||||
auto engine = new Engine();
|
||||
|
||||
auto loader = QSharedPointer<FileSystemTemplateLoader>::create();
|
||||
loader->setTemplateDirs( {"/usr/share/myapp/templates"} );
|
||||
engine->addTemplateLoader( loader );
|
||||
|
||||
engine->addPluginPath( "/usr/lib/myapp" );
|
||||
|
||||
auto template1 = engine->newTemplate( "Template content", "template name" );
|
||||
|
||||
auto template2 = engine->loadByName( "templatefile.html" );
|
||||
@endcode
|
||||
|
||||
Once it is configured, the **%Engine** can be used to create new templates by
|
||||
name by loading the templates with the @ref loadByName method, or by defining
|
||||
the content in the @ref newTemplate method.
|
||||
|
||||
By default the builtin tags and filters distributed with %KTextTemplate are
|
||||
available in all templates without using the @gr_tag{load} tag in the
|
||||
template. These pre-loaded libraries may be configured if appropriate to the
|
||||
application. For example, an application which defines its own tags and
|
||||
filters may want them to be always available, or it may be desirable to
|
||||
restrict the features available to template authors by removing built in
|
||||
libraries.
|
||||
|
||||
Different **%Engine** objects can be used to create templates with differing
|
||||
configurations.
|
||||
|
||||
@section smart_trim Insignificant whitespace
|
||||
|
||||
The output of rendering a template depends on the content of the template. In
|
||||
some cases when generating content in which whitespace is significant, this
|
||||
can have undesired effects. For example, given a template to generate C++ code
|
||||
like:
|
||||
|
||||
@verbatim
|
||||
class MyClass {
|
||||
{# This loop creates the #}
|
||||
{# methods in the class #}
|
||||
{% for method in methods %}
|
||||
{% if method.hasDox %}
|
||||
{{ method.dox }}
|
||||
{% endif %}
|
||||
{{ method.signature }}
|
||||
{% endfor %}
|
||||
};
|
||||
@endverbatim
|
||||
|
||||
The output would have a lot of whitespace which is not necessarily wanted.
|
||||
|
||||
@code
|
||||
class MyClass {
|
||||
|
||||
|
||||
|
||||
|
||||
void foo() const;
|
||||
|
||||
};
|
||||
@endcode
|
||||
|
||||
It is possible to strip insignificant whitespace by enabling the smartTrim
|
||||
feature with @ref setSmartTrimEnabled. When enabled the output will not
|
||||
contain a newline for any line in the template which has only one token of
|
||||
template syntax, such as a comment, tag or variable.
|
||||
|
||||
@code
|
||||
class MyClass {
|
||||
|
||||
void foo() const;
|
||||
};
|
||||
@endcode
