Detailed Description

Shows a filename as an editable text box, with a 'browse' button and a drop-down list for recently selected files.

A handy component for dialogue boxes where you want the user to be able to select a file or directory.

Attach an FilenameComponentListener using the addListener() method, and it will get called each time the user changes the filename, either by browsing for a file and clicking 'ok', or by typing a new filename into the box and pressing return.

const String & fileBrowserWildcard,
const String & enforcedSuffix,
const String & textWhenNothingSelected )

Creates a FilenameComponent.

Parameters
namethe name for this component.
currentFilethe file to initially show in the box
canEditFilenameif true, the user can manually edit the filename; if false, they can only change it by browsing for a new file
isDirectoryif true, the file will be treated as a directory, and an appropriate directory browser used
isForSavingif true, the file browser will allow non-existent files to be picked, as the file is assumed to be used for saving rather than loading
fileBrowserWildcarda wildcard pattern to use in the file browser - e.g. "*.txt;*.foo". If an empty string is passed in, then the pattern is assumed to be "*"
enforcedSuffixif this is non-empty, it is treated as a suffix that will be added to any filenames that are entered or chosen
textWhenNothingSelectedthe message to display in the box before any filename is entered. (This will only appear if the initial file isn't valid)

Destructor.

Member Function Documentation

◆ getCurrentFile()

File FilenameComponent::getCurrentFile ( ) const

Returns the currently displayed filename.

◆ getCurrentFileText()

String FilenameComponent::getCurrentFileText ( ) const

Returns the raw text that the user has entered.

◆ setCurrentFile()

void FilenameComponent::setCurrentFile ( File newFile,
bool addToRecentlyUsedList,
NotificationType notification = sendNotificationAsync )

Changes the current filename.

Parameters
newFilethe new filename to use
addToRecentlyUsedListif true, the filename will also be added to the drop-down list of recent files.
notificationwhether to send a notification of the change to listeners. A notification will only be sent if the filename has changed.

◆ setFilenameIsEditable()

void FilenameComponent::setFilenameIsEditable ( bool shouldBeEditable)

Changes whether the use can type into the filename box.

◆ setDefaultBrowseTarget()

void FilenameComponent::setDefaultBrowseTarget ( const File & newDefaultDirectory)

Sets a file or directory to be the default starting point for the browser to show.

This is only used if the current file hasn't been set.

◆ getLocationToBrowse()

virtual File FilenameComponent::getLocationToBrowse ( )
virtual

This can be overridden to return a custom location that you want the dialog box to show when the browse button is pushed.

The default implementation of this method will return either the current file (if one has been chosen) or the location that was set by setDefaultBrowseTarget().

◆ getRecentlyUsedFilenames()

StringArray FilenameComponent::getRecentlyUsedFilenames ( ) const

Returns all the entries on the recent files list.

This can be used in conjunction with setRecentlyUsedFilenames() for saving the state of this list.

See also
setRecentlyUsedFilenames

◆ setRecentlyUsedFilenames()

void FilenameComponent::setRecentlyUsedFilenames ( const StringArray & filenames)

Sets all the entries on the recent files list.

This can be used in conjunction with getRecentlyUsedFilenames() for saving the state of this list.

See also
getRecentlyUsedFilenames, addRecentlyUsedFile

◆ addRecentlyUsedFile()

void FilenameComponent::addRecentlyUsedFile ( const File & file)

Adds an entry to the recently-used files dropdown list.

If the file is already in the list, it will be moved to the top. A limit is also placed on the number of items that are kept in the list.

See also
getRecentlyUsedFilenames, setRecentlyUsedFilenames, setMaxNumberOfRecentFiles

◆ setMaxNumberOfRecentFiles()

void FilenameComponent::setMaxNumberOfRecentFiles ( int newMaximum)

Changes the limit for the number of files that will be stored in the recent-file list.

◆ setBrowseButtonText()

void FilenameComponent::setBrowseButtonText ( const String & browseButtonText)

Changes the text shown on the 'browse' button.

By default this button just says "..." but you can change it. The button itself can be changed using the look-and-feel classes, so it might not actually have any text on it.

◆ addListener()

void FilenameComponent::addListener ( FilenameComponentListener * listener)

Adds a listener that will be called when the selected file is changed.

◆ removeListener()

void FilenameComponent::removeListener ( FilenameComponentListener * listener)

Removes a previously-registered listener.

◆ setTooltip()

void FilenameComponent::setTooltip ( const String & newTooltip)
overridevirtual

Gives the component a tooltip.

Reimplemented from SettableTooltipClient.

◆ paintOverChildren()

void FilenameComponent::paintOverChildren ( Graphics & g)
overridevirtual

Components can override this method to draw over the top of their children.

For most drawing operations, it's better to use the normal paint() method, but if you need to overlay something on top of the children, this can be used.

See also
paint, Graphics

Reimplemented from Component.

◆ resized()

void FilenameComponent::resized ( )
overridevirtual

Called when this component's size has been changed.

A component can implement this method to do things such as laying out its child components when its width or height changes.

The method is called synchronously as a result of the setBounds or setSize methods, so repeatedly changing a components size will repeatedly call its resized method (unlike things like repainting, where multiple calls to repaint are coalesced together).

If the component is a top-level window on the desktop, its size could also be changed by operating-system factors beyond the application's control.

See also
moved, setSize

Reimplemented from Component.

◆ lookAndFeelChanged()

void FilenameComponent::lookAndFeelChanged ( )
overridevirtual

Called to let the component react to a change in the look-and-feel setting.

When the look-and-feel is changed for a component, this method, repaint(), and colourChanged() are called on the original component and all its children recursively.

It can also be triggered manually by the sendLookAndFeelChange() method, in case an application uses a LookAndFeel class that might have changed internally.

sendLookAndFeelChange, getLookAndFeel

Reimplemented from Component.

◆ isInterestedInFileDrag()

bool FilenameComponent::isInterestedInFileDrag ( const StringArray & files)
overridevirtual

Callback to check whether this target is interested in the set of files being offered.

Note that this will be called repeatedly when the user is dragging the mouse around over your component, so don't do anything time-consuming in here, like opening the files to have a look inside them!

Parameters
filesthe set of (absolute) pathnames of the files that the user is dragging
Returns
true if this component wants to receive the other callbacks regarding this type of object; if it returns false, no other callbacks will be made.

Implements FileDragAndDropTarget.

◆ filesDropped()

void FilenameComponent::filesDropped ( const StringArray & files,
int x,
int y )
overridevirtual

Callback to indicate that the user has dropped the files onto this component.

When the user drops the files, this get called, and you can use the files in whatever way is appropriate.

Note that after this is called, the fileDragExit method may not be called, so you should clean up in here if there's anything you need to do when the drag finishes.

Parameters
filesthe set of (absolute) pathnames of the files that the user is dragging
xthe mouse x position, relative to this component
ythe mouse y position, relative to this component

Implements FileDragAndDropTarget.

◆ fileDragEnter()

void FilenameComponent::fileDragEnter ( const StringArray & files,
int x,
int y )
overridevirtual

Callback to indicate that some files are being dragged over this component.

This gets called when the user moves the mouse into this component while dragging.

Use this callback as a trigger to make your component repaint itself to give the user feedback about whether the files can be dropped here or not.

Parameters
filesthe set of (absolute) pathnames of the files that the user is dragging
xthe mouse x position, relative to this component
ythe mouse y position, relative to this component

Reimplemented from FileDragAndDropTarget.

◆ fileDragExit()

void FilenameComponent::fileDragExit ( const StringArray & files)
overridevirtual

Callback to indicate that the mouse has moved away from this component.

This gets called when the user moves the mouse out of this component while dragging the files.

If you've used fileDragEnter() to repaint your component and give feedback, use this as a signal to repaint it in its normal state.

Parameters
filesthe set of (absolute) pathnames of the files that the user is dragging

Reimplemented from FileDragAndDropTarget.

◆ createKeyboardFocusTraverser()

std::unique_ptr< ComponentTraverser > FilenameComponent::createKeyboardFocusTraverser ( )
overridevirtual

Creates a ComponentTraverser object to use to determine the logic by which keyboard focus should be passed from this component.

The default implementation of this method will return an instance of KeyboardFocusTraverser if this component is a keyboard focus container (as determined by the setFocusContainerType() method). If the component isn't a keyboard focus container, then it will recursively call createKeyboardFocusTraverser() on its parents.

If you override this to return a custom traverser object, then this component and all its sub-components will use the new object to make their keyboard focusing decisions.

Reimplemented from Component.
