Namespaces
	Util
	DynExp's Util namespace contains commonly used functions and templates as well as extensions to Qt and its widgets.

Functions
const QLocale &	Util::GetDefaultQtLocale ()
	Returns the default locale properties to be assigned to Qt widgets. More...
void	Util::ActivateWindow (QWidget &Widget)
	Renders a window active and brings it to the front. More...
DOM functions
These functions can be used to walk through an (XML-)DOM tree.
std::vector< QDomNode >	Util::GetChildDOMNodes (const QDomElement &Parent, const QString &ChildTagName)
	Finds child nodes with a certain tag name. More...
QDomNode	Util::GetSingleChildDOMNode (const QDomElement &Parent, const QString &ChildTagName)
	Finds a single child node with a certain tag name. More...
QDomElement	Util::GetSingleChildDOMElement (const QDomElement &Parent, const QString &ChildTagName)
	Behaves like GetSingleChildDOMNode() but returns the node converted to a DOM element. More...
std::string	Util::GetStringFromDOMElement (const QDomElement &Parent, const QString &ChildTagName)
	Behaves like GetSingleChildDOMElement() but returns the text from a DOM element. More...
template<>
std::string	Util::GetTFromDOMElement (const QDomElement &Parent, const QString &ChildTagName)
	Behaves like GetSingleChildDOMElement() but returns the content from a DOM element converted to a certain type using Util::StrToT(). More...
QDomAttr	Util::GetDOMAttribute (const QDomElement &Element, const QString &AttributeName)
	Extracts an attribute from a DOM element. More...
std::string	Util::GetStringFromDOMAttribute (const QDomElement &Element, const QString &AttributeName)
	Behaves like GetDOMAttribute() but returns the text from the attribute. More...
template<>
std::string	Util::GetTFromDOMAttribute (const QDomElement &Element, const QString &AttributeName)
	Behaves like GetDOMAttribute() but returns the content from an attribute converted to a certain type using Util::StrToT(). More...
File open and save dialogs
QString	Util::PromptOpenFilePath (QWidget *Parent, const QString &Title, const QString &DefaultSuffix, const QString &NameFilter, const QString &InitialDirectory="")
	Opens a file dialog to ask the user to select a single existing file. More...
QString	Util::PromptSaveFilePath (QWidget *Parent, const QString &Title, const QString &DefaultSuffix, const QString &NameFilter, const QString &InitialDirectory="")
	Works as PromptOpenFilePath() but asks the user to select a single file which does not need to exist. More...
QString	Util::PromptSaveFilePathModule (DynExp::QModuleWidget *Parent, const QString &Title, const QString &DefaultSuffix, const QString &NameFilter)
	Works as PromptOpenFilePath() but asks the user to select a single file which does not need to exist. Furthermore, the dialog automatically derives the initial directory using QModuleWidget::GetDataSaveDirectory() and sets the new global directory for saving data to the folder containing the selected file when the user accepts the dialog. More...
Image manipulation
QImage	Util::QImageFromBlobData (BlobDataType &&BlobData, int Width, int Height, int BytesPerLine, QImage::Format Format)
	Converts raw pixel data stored in a Util::BlobDataType object to a QImage transfering the ownership of BlobData's content. More...
ImageHistogramType	Util::ComputeIntensityHistogram (const QImage &Image)
	Computes an intensity (grayscale) histogram from a QImage object. More...
ImageRGBHistogramType	Util::ComputeRGBHistogram (const QImage &Image)
	Computes a RGB histogram from a QImage object. More...
ImageHistogramType	Util::ConvertRGBToIntensityHistogram (const ImageRGBHistogramType &RGBHistogram)
	Computes an intensity (grayscale) histogram from a RGB histogram. More...
QPolygonF	Util::MakeCrossPolygon (QPointF Center, unsigned int ArmLength)
	Returns a QPolygonF representing a cross-style marker. More...
Reading and writing files
bool	Util::SaveToFile (const QString &Filename, std::string_view Text)
	Saves a std::string_view to a file (using QFile). Creates a new file or truncates an existing file's content. More...
std::string	Util::ReadFromFile (const QString &Filename)
	Reads the entire content from a text file. More...
std::string	Util::ReadFromFile (const std::string &Filename)
	Reads the entire content from a text file. More...
std::string	Util::ReadFromFile (const std::filesystem::path &Filename)
	Reads the entire content from a text file. More...
