Signals: - 'fileOpened': a path to an existing file has been selected by the user, or the widget's initialization process (carried out in 'loadSettings') has been completed. Use 'getFilePath' to get the file's path. Note: if the widget's initialization process fails due to missing settings file or non-existent file path, this signal will still be fired, and 'getFilePath' will return 'None' in that case. - 'fileCreated': A non-existent file path has been selected by the user. Use 'getFilePath' to get the path, and 'invalidateFilePath' to report failure of creation of the requested file.cCsétj||ƒ||_||_d|_d|_tƒ}|dk ret|ƒ}|j |ƒnd}t ƒ|_ |j j t ƒ|j |j ƒttjdƒdƒ|_|jjj|jƒ|jjƒ|j |jƒttjdƒdƒ|_|jjtƒ|jjj|jƒ|jjƒ|j |jƒttjdƒdƒ|_|dk r}|jj|ƒn|jjj|jƒ|j |jƒ|jddddƒ|j|ƒ|dk rå|j|jƒndS(Ntnewttreloadtopeni( tQWidgett__init__tfileNameFiltertopenDialogCaptiontNonetcreateDialogCaptiont lastFileDirt QHBoxLayouttQLabelt addWidgett QLineEditt filePathEditt setReadOnlytTruet QPushButtonRtloadIcont createButtontclickedtconnecttonCreateButtonClickedthidet reloadButtont setEnabledtFalsetonReloadButtonClickedt openButtont setToolTiptonOpenButtonClickedtsetContentsMarginst setLayouttsetBuddy(tselft labelTextR R topenButtonToolTiptparenttlayoutt filePathLabel((s"code\common\FileSelectionWidget.pyR 4s>             cCs9||_|dk r(|jj|ƒn|jjƒdS(sÜDisplay a button that will make it possible to select a non-existent file path.
