NSToolbar

Toolbars add a nice professional look to an application. Shown above is a screenshot from a simple demo of toolbars using PyObjC. The toolbar's delegate (MyToolbarDelegate) implements the three required methods. In this example, we add a custom toolbar item called "Analyze":

def toolbar_itemForItemIdentifier_willBeInsertedIntoToolbar_( self, toolbar, identifier, flag): if identifier == "Analyze": item = NSToolbarItem.alloc().initWithItemIdentifier_( "Analyze") item.setLabel_("Analyze") item.setPaletteLabel_("Analyze") item.setToolTip_("Analyze Your Gene") item.setImage_(NSImage.imageNamed_("GeneFinderIcon")) item.setTarget_(self.AD) sel = 'analyze:' item.setAction_(sel) return item return None def toolbarDefaultItemIdentifiers_(self, toolbar): return [NSToolbarCustomizeToolbarItemIdentifier, NSToolbarShowColorsItemIdentifier, "Analyze"] def toolbarAllowedItemIdentifiers_(self, toolbar): return [NSToolbarCustomizeToolbarItemIdentifier, NSToolbarShowColorsItemIdentifier, "Analyze", NSToolbarPrintItemIdentifier, NSToolbarShowFontsItemIdentifier, NSToolbarSpaceItemIdentifier, NSToolbarSeparatorItemIdentifier ]

There is an icon added to the project in Resources.

We also need to initialize the toolbar and attach it to the window. I do this in a separate class called MyToolbarController. (All the outlets are set up as you'd expect, in the xib file). This one is relayed through the AppDelegate (AD).

def awakeFromNib(self): self.toolbar = NSToolbar.alloc().initWithIdentifier_("toolbar") self.toolbar.setDelegate_(self.AD.myToolbarDelegate) print "delegate", self.toolbar.delegate() self.toolbar.insertItemWithItemIdentifier_atIndex_("Analyze", 0) for item in self.toolbar.items(): print item.itemIdentifier() self.toolbar.setDisplayMode_(NSToolbarDisplayModeIconOnly) # this allows customization as you'd expect self.toolbar.setAllowsUserCustomization_(True) self.toolbar.setAutosavesConfiguration_(True) self.myWindow.setToolbar_(self.toolbar) print "visible?", self.toolbar.isVisible()
