Sets the minimum column width in pixels and adjusts subviews.

See Also: -minColumnWidth


setPath: 

- (BOOL) setPath: (NSString*)path;
Availability: OpenStep

Parses path and selects corresponding items in the NSBrowser columns.

This is the primary mechanism for programmatically updating the selection of a browser. It should result in the browser cells corresponding to the components being selected, and the browser columns up to the end of path (and just beyond if the last selected cell's [NSBrowserCell -isLeaf] returns YES).
It does not result in the browsers action being sent to its target, just in a change to the browser selection and display.

If path begins with the -pathSeparator then it is taken to be absolute and the first component in it is expected to denote a cell in column zero. Otherwise it is taken to be relative to the currently selected column.

Empty components (ie where a -pathSeparator occurs immediately after another or at the end of path) are simply ignored.

The receivers delegate is asked to select each cell in turn using the -browser:selectCellWithString:inColumn: method (if it implements it). If this call to the delegate returns NO then the attempt to set the path fails.
If the delegate does not implement the method, the browser attempts to locate and select the cell itself, and the method fails if it is unable to locate the cell by matching its [NSCell -stringValue] with the component of the path.

The method returns YES if path contains no components or if a cell corresponding to the path was found. Otherwise it returns NO.


setPathSeparator: 

- (void) setPathSeparator: (NSString*)aString;
Availability: OpenStep

Sets the path separator to newString. The default is "/".

See Also: -pathSeparator

Availability: Not in OpenStep/MacOS-X

Description forthcoming.

setReusesColumns: 

- (void) setReusesColumns: (BOOL)flag;
Availability: OpenStep

If flag is YES, prevents NSMatrix objects from being freed when their columns are unloaded, so they can be reused. By default a NSBrowser does not reuses their columns.

See Also: -reusesColumns [NSMatrix -renewRows:columns:]


setSendsActionOnArrowKeys: 

- (void) setSendsActionOnArrowKeys: (BOOL)flag;
Availability: OpenStep

Sets whether pressing an arrow key will cause the action message to be sent (in addition to causing scrolling). By default YES.

See Also: -sendsActionOnArrowKeys -setAcceptsArrowKeys: [NSControl -setAction:] [NSControl -action]


setSeparatesColumns: 

- (void) setSeparatesColumns: (BOOL)flag;
Availability: OpenStep

See Also: -setTakesTitleFromPreviousColumn: -selectedCellInColumn:


tile 

- (void) tile;
Availability: OpenStep

Adjusts the various subviews of NSBrowser-scrollers, columns, titles, and so on-without redrawing. Your code shouldn't send this message. It's invoked any time the appearance of the NSBrowser changes.
