const istd::IChangeable dataObjectPtr,
int  flags,
QStringList &  allExt,
QStringList &  result,
bool  allowCommonDescription = true 
)
static

Append filters extracted from file loader to Qt filter list accepted by QFileDialog.

Parameters
loaderfile loader.
allExtoutput list of all filters from extensions separated using semicolon (for example '*.bmp;*.png').
resultinput/output list of filters with description separated with next line character.
Returns
number of filters.

virtual bool ifilegui::CFileDialogLoaderComp::GetFileExtensions ( QStringList &  result,
const istd::IChangeable dataObjectPtr = NULL,
int  flags = -1,
bool  doAppend = false 
) const
virtual

Get file extensions supported by this loader.

Parameters
resultlist of extensions, e.g. {"txt", "doc"}.
dataObjectPtroptional pointer to data object for which all possible extensions are requested. It can be NULL if any object is meant.
flagsset of flags

Parameters
doAppendif true, list of extensions should be appended to existing list.
