## page was renamed from zhArticleTemplate ##language:zh #pragma section-numbers on ::-- ehu4ever [<>] <> = 普通货色 = 按钮到处都是，真是太太普通了。用gtk.Button()就可以建立一个按钮了，还可以顺便加一个文本标签，想造一个空白的按钮也随你便。你也可在你的按钮上铺上图片。 建立一个按钮就是这么简单： {{{ button = gtk.Button(label=None, stock=None) }}} 在很多时候，按钮上还会有一个指示图标。就是以下的其中一个： {{{ STOCK_DIALOG_INFO STOCK_DIALOG_WARNING STOCK_DIALOG_ERROR STOCK_DIALOG_QUESTION STOCK_DND STOCK_DND_MULTIPLE STOCK_ADD STOCK_APPLY STOCK_BOLD STOCK_CANCEL STOCK_CDROM STOCK_CLEAR STOCK_CLOSE STOCK_CONVERT STOCK_COPY STOCK_CUT STOCK_DELETE STOCK_EXECUTE STOCK_FIND STOCK_FIND_AND_REPLACE STOCK_FLOPPY STOCK_GOTO_BOTTOM STOCK_GOTO_FIRST STOCK_GOTO_LAST STOCK_GOTO_TOP STOCK_GO_BACK STOCK_GO_DOWN STOCK_GO_FORWARD STOCK_GO_UP STOCK_HELP STOCK_HOME STOCK_INDEX STOCK_ITALIC STOCK_JUMP_TO STOCK_JUSTIFY_CENTER STOCK_JUSTIFY_FILL STOCK_JUSTIFY_LEFT STOCK_JUSTIFY_RIGHT STOCK_MISSING_IMAGE STOCK_NEW STOCK_NO STOCK_OK STOCK_OPEN STOCK_PASTE STOCK_PREFERENCES STOCK_PRINT STOCK_PRINT_PREVIEW STOCK_PROPERTIES STOCK_QUIT STOCK_REDO STOCK_REFRESH STOCK_REMOVE STOCK_REVERT_TO_SAVED STOCK_SAVE STOCK_SAVE_AS STOCK_SELECT_COLOR STOCK_SELECT_FONT STOCK_SORT_ASCENDING STOCK_SORT_DESCENDING STOCK_SPELL_CHECK STOCK_STOP STOCK_STRIKETHROUGH STOCK_UNDELETE STOCK_UNDERLINE STOCK_UNDO STOCK_YES STOCK_ZOOM_100 STOCK_ZOOM_FIT STOCK_ZOOM_IN STOCK_ZOOM_OUT }}} button.py是一个使用gtk.Button()建立按钮的例子，有的按钮上的文本，有的按钮上有图片，也可以两样都有： ||Figure 6.1. Button with Pixmap and Label|| ||{{attachment:button.png}}|| 以下是源代码： {{{#!python #!/usr/bin/env python # example-start buttons buttons.py import pygtk pygtk.require('2.0') import gtk # Create a new hbox with an image and a label packed into it # and return the box. def xpm_label_box(parent, xpm_filename, label_text): # Create box for xpm and label box1 = gtk.HBox(False, 0) box1.set_border_width(2) # Now on to the image stuff image = gtk.Image() image.set_from_file(xpm_filename) # Create a label for the button label = gtk.Label(label_text) # Pack the pixmap and label into the box box1.pack_start(image, False, False, 3) box1.pack_start(label, False, False, 3) image.show() label.show() return box1 class Buttons: # Our usual callback method def callback(self, widget, data=None): print "Hello again - %s was pressed" % data def __init__(self): # Create a new window self.window = gtk.Window(gtk.WINDOW_TOPLEVEL) self.window.set_title("Image'd Buttons!") # It's a good idea to do this for all windows. self.window.connect("destroy", lambda wid: gtk.main_quit()) self.window.connect("delete_event", lambda a1,a2:gtk.main_quit()) # Sets the border width of the window. self.window.set_border_width(10) # Create a new button button = gtk.Button() # Connect the "clicked" signal of the button to our callback button.connect("clicked", self.callback, "cool button") # This calls our box creating function box1 = xpm_label_box(self.window, "info.xpm", "cool button") # Pack and show all our widgets button.add(box1) box1.show() button.show() self.window.add(button) self.window.show() def main(): gtk.main() return 0 if __name__ == "__main__": Buttons() main() }}} Lines 12-34 define the xpm_label_box() helper function which creates a horizontal box with a border width of 2 (lines 14-15), populates it with an image (lines 22-23) and a label (line 26). Lines 36-70 define the Buttons class. Lines 41-70 define the instance initialization method which creates a window (line 43), sets the title (line 45), connects the "delete_event" and "destroy" signals (lines 48-49). Line 55 creates the button without a label. Its "clicked" signal gets connected to the callback() method in line 58. The xpm_label_box() function is called in line 61 to create the image and label to put in the button in line 64. The xpm_label_box() function could be used to pack xpm's and labels into any widget that can be a container. The Button widget has the following signals: {{{ pressed - emitted when pointer button is pressed within Button widget released - emitted when pointer button is released within Button widget clicked - emitted when pointer button is pressed and then released within Button widget enter - emitted when pointer enters Button widget leave - emitted when pointer leaves Button widget }}}
