allExt	output list of all filters from extensions separated using semicolon (for example '.bmp;.png').
result	input/output list of filters with description separated with next line character.

Returns: number of filters.

overridevirtual

Returns true if object dataObject can be loaded/saved.

Parameters

dataObjectPtr	optional pointer to data object should be loaded/stored. It can be NULL if any object is meant.
filePathPtr	optional pointer to file should be loaded/stored. It can be NULL if any file is meant. If it points at empty string, anonymous loading is mean.
flags	combination of flags defined in `QueryFlags` and `ifile::IFileTypeInfo::QueryFlags`.
beQuiet	if true, no user message output is allowed.

Implements ifile::IFilePersistence.

Implements ifile::IFilePersistence.

◆ OnComponentCreated()

virtual void ifilegui::CFileDialogLoaderComp::OnComponentCreated ( )

overrideprotectedvirtual

Called when component is created.

		const QString &	filePath = `QString()`,
		ibase::IProgressManager *	progressManagerPtr = `NULL`
	)		const

overridevirtual

This function saves data data to file filePath.

Returns: File saving state.
