Detailed Description

Dialog class.

Library: ilvadvgdt

The IlvFileBrowser class allows you to dynamically specify which file selector to use from IlvFileSelector (when available) or IlvFileChooser, through a unique programming interface.

You can select a file browser in code in two ways: either in the IlvFileBrowser constructor, or with the setOption() member function. You can also select a file browser at run time using the ILVFILEBROWSEROPTIONS environment variable or resource. The possible values for this environment variable are UseDefault, UseAlwaysSystemDialog or UseAlwaysViewsDialog. For details, see the IlvFileBrowserOption enumeration.

See also
IlvFileSelector, IlvFileChooser, IlvFileBrowserOption.

Constructor & Destructor Documentation

§ IlvFileBrowser()

IlvFileBrowser::IlvFileBrowser ( IlvDisplay display,
IlvSystemView  transientFor,
const char *  dir = 0,

const char *const *  filters = 0,
const char *const *  messages = 0,
IlvFileBrowserOption  useSystemDlg = IlvUseDefault 
)

Constructor.

Initializes a new instance of the IlvFileBrowser class that will display either the system dialog or the Rogue Wave Views built-in dialog, according to the parameter useSystemDlg.

Parameters
displayThe connection to the display.
transientForThe system view for which the dialog is transient (see IlvView).
dirThe directory to be browsed.
nbThe numbers of filters and related messages specified by the filters and messages parameters, respectively.
filtersAn array of strings representing the possible filters.

Member Function Documentation

§ ensureInScreen()

void IlvFileBrowser::ensureInScreen ( IlvPos  xMargin = 0,
IlvPos  yMargin = 0 
)

Ensures that the file browser remains visible.

This function moves the file browser so that it remains visible on the screen. If the file browser is higher than the screen, it will not move in the y direction. If the file browser is wider than the screen, it will not move in the x direction. xMargin and yMargin define margin distances that the file browser location must respect, as if the screen were 2*xMargin pixels less wide, and 2*yMargin pixels less high.
If the file browser is already entirely visible on the screen with the margins respected, this function does nothing.

Parameters
xMarginThe horizontal margin.
yMarginThe vertical margin.

§ get()

Displays the file browser as a modal dialog and returns a string.

Returns
The full path name selected or 0 if the dialog was canceled. This string must never be deleted or modified.
