gtkFileSelection(title = NULL, show = TRUE)GtkFileSelection should be used to retrieve file or directory names from
the user. It will create a new dialog window containing a directory list,
and a file list corresponding to the current working directory. The filesystem
can be navigated using the directory list or the drop-down history menu.
Alternatively, the TAB key can be used to navigate using filename
completion - common in text based editors such as emacs and jed.
File selection dialogs are created with a call to gtkFileSelectionNew.
The default filename can be set using gtkFileSelectionSetFilename and the selected filename retrieved using gtkFileSelectionGetFilename.
Use gtkFileSelectionComplete to display files and directories
that match a given pattern. This can be used for example, to show only
*.txt files, or only files beginning with gtk*.
Simple file operations; create directory, delete file, and rename file, are available from buttons at the top of the dialog. These can be hidden using gtkFileSelectionHideFileopButtons and shown again using gtkFileSelectionShowFileopButtons.
# Getting a filename from a user
# Note how much easier GtkFileChooser is to usestore_filename <- function(widget, file_selector) { selected_filename <- file_selector$getFilename(); print(paste("Selected filename:", selected_filename)) }
create_file_selection <- function() {
# Create the selector file_selector <- gtkFileSelection("Please select a file for editing.", show = F) gSignalConnect(file_selector[["ok_button"]], "clicked", store_filename, file_selector) # Ensure that the dialog box is destroyed when the user clicks a button. gSignalConnect(file_selector[["ok_button"]], "clicked", gtkWidgetDestroy, file_selector, user.data.first = T)
gSignalConnect(file_selector[["cancel_button"]], "clicked", gtkWidgetDestroy, file_selector, user.data.first = T) # Display that dialog file_selector$show() }
gtkFileSelection is the equivalent of gtkFileSelectionNew.
