Custom button for Combobox

Ubitux — 2008-10-07T11:14:49

Hi, I'm trying to do this : http://www.pygtk.org/pygtk2tutorial/figures/comboboxwrap.png but I would like to have a customised button. The popup() method does not seem to work when I connect it to a customised gtk.Button() if the combobox is hidden (in fact I just want to have the button of the combobox hidden). Maybe there is other way to do what I want. I had a look to gtk.Menu() but there is not wrap mode like the combobox has (to have the same render of the screenshot above). Another thing I tried is to use the set_active() method on the item I always want to have by default on the button. But the problem is that the 'changed' signal does not work on the default item (of course). It seems there is no 'selected' signal which act as the 'changed' one but with the unchanged item too... So if you have any idea, I'll be very gratefull, it's been a while I'm on this problem... Another thing : I think I found a mistake in the documentation while looking for my problem. On this page : http://www.pygtk.org/docs/pygtk/class-gtkcombobox.html the propery "popup-shown" is marked as Read-Write, but it seems to be readonly : TypeError: property 'popup-shown' is not writable. Thanks.

Can you get signal_autoconnect to warn about missinghandlers?

2008-10-06T15:46:18

As I work on a GUI app I go back and forth between Python and Glade. Sometimes I do a bit of refactoring. The combination of tasks means I can forget to implement a signal handler or leave one behind somewhere else while refactoring. Is it possible to coax signal_autoconnect to warn about signal handlers defined in the widget tree but which are missing from the dict or instance argument? Thanks,

completion and TreeStore child element

Alessandro Dentella — 2008-10-05T18:09:29

Hi, I wanted to add grouping in a completion. I used a TreeStore in the completion, added correctly father/child element... but the completion shows it collapsed. I see that completion does not have .expand_all() that is a method of TreeView... is it any possibile? And in case it is possible, is it any possible for the used to collapse single entries?

gtk.ComboBox with RELIEF_NONE

Darren Hart — 2008-10-02T20:26:03

I've been trying to find a way to create a combobox with no relief (like the sidebar selector in nautilus). So far I haven't found a way to set this property for a gtk.ComboBox. Is there a way? From what I can see so far I'd have to use a container button with a label and a gtk arrow and a menu that pops-up on click.... yuk...

Connecting gtk.MenuItems to existing accelerators

Walter Leibbrandt — 2008-10-02T08:41:17

Hi, Much more than the subject, I cannot explain well, so I'll let the code do the talking:


        self.accel_group = gtk.AccelGroup()
        self.main_window.add_accel_group(self.accel_group)

        gtk.accel_map_add_entry("/Edit/Undo", gtk.keysyms.z, 
gdk.CONTROL_MASK)
        gtk.accel_map_add_entry("/Edit/Search", gtk.keysyms.F3, 0)
        gtk.accel_map_add_entry("/Navigation/Up", 
gtk.keysyms.Up, gdk.CONTROL_MASK)
        gtk.accel_map_add_entry("/Navigation/Down", 
gtk.keysyms.Down, gdk.CONTROL_MASK)
        gtk.accel_map_add_entry("/Navigation/PgUp", 
gtk.keysyms.Page_Up, gdk.CONTROL_MASK)
        gtk.accel_map_add_entry("/Navigation/PgDown", 
gtk.keysyms.Page_Down, gdk.CONTROL_MASK)

        self.accel_group.connect_by_path("/Edit/Undo", 
self._on_undo)
        self.accel_group.connect_by_path("/Edit/Search", 
self._on_search)

This, in its own, works fine, but then I added "Edit" and "Navigation" menu's via Glade and added the following code directly below the block above (self.gui is the Glade.XML object):


        # gtk.Menu's:
        self.gui.get_widget('menu_edit').set_accel_group(self.accel_group)
        
self.gui.get_widget('menu_navigation').set_accel_group(self.accel_group)

        # gtk.MenuItems:
        
self.gui.get_widget('mnu_undo').set_accel_path("/Edit/Undo")
        
self.gui.get_widget('mnu_search').set_accel_path("/Edit/Search")
        
self.gui.get_widget('mnu_up').set_accel_path("/Navigation/Up")
        
self.gui.get_widget('mnu_down').set_accel_path("/Navigation/Down")
        
self.gui.get_widget('mnu_page_up').set_accel_path("/Navigation/PgUp")
        
self.gui.get_widget('mnu_page_down').set_accel_path("/Navigation/PgDown")

The accelerators still work, but the menu items, once activated, does nothing, even though the correct keyboard shortcuts are displayed in the menu's. I realize that only "Undo" and "Search" have handlers defined in the given snippets, but even they do not work. I guess my question is how to use the already-connected accelerator handlers (self._on_undo and self._on_search) when the related menu item is activated. Thanks in advance. Regards,

Cell renderer repository?

Alessandro Dentella — 2008-10-01T15:22:58

Hi, I'm in the need to write a cell render for what I believe a common thing: a text editor for log text that is not easy to edit in the standard CellRendererText. I'm wandering if there exist already such a renderer or a repository of cell renderer ready to use. A second one I need is Date/DateTimeRenderer. I guess I'm not the first one that need such a beast... sandro _______________________________________________ pygtk mailing list pygtk< at >daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

Hi, I'm trying to freeze an application using py2exe. All works fine, except for 2 modules which are not retreived once the application is deployed. Here are the errors: ImportError: "MemoryLoadLibrary failed loading bluetooth\_msbt.pyd" and ImportError: MemoryLoadLibrary failed loading gobject\_gobject.pyd" I also have this error if I try to import the bluetooth module under IPython, so I don't expect it to be embedded in the frozen app... But the _msbt.pyd module does exist! Why is it not loaded? For the second one, I don't understand. I attached my setup file. As you can see, the gobject module is added to the list of modules to include. So, why can't it be load?

Memory leak when using pangocairo for animation

Seth Remington — 2008-09-30T13:28:51

Hello, I am not a member of the list but can confirm the OP's discovery of the memory leak. I was Googling for this and found this mailing list post and then noticed that the date was only three days ago (thanks for the quick indexing Google) and thought I should chime in. I have a custom cairo widget inheriting from a gtk.DrawingArea that displays some text and refreshes very frequently. Using cairo's built-in text rendering (i.e. show_text()) I do not see the memory leak but when I switched to using pangocairo then I saw the massive memory growth. Here's the code snipets: NO MEMORY LEAK ============== context.select_font_face('sans-serif') context.set_font_size(20) loop_name = str(self.loop.loop_number + 1) (x, y, text_width, text_height, dx, dy) = context.text_extents(loop_name) context.move_to(2, text_height + 2) context.set_source_rgb(0.9, 0.9, 0.9) context.show_text(loop_name) MEMORY LEAK =========== font = "Sans Serif 20" markup = "%d" % (font, self.loop.loop_number + 1) pango_context = pangocairo.CairoContext(context) layout = pango_context.create_layout() layout.set_markup(markup) layout.set_alignment(pango.ALIGN_LEFT) context.move_to(2, 2) context.set_source_rgb(0.9, 0.9, 0.9) pango_context.show_layout(layout) -Seth ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.

Downloading a file without locking the GUI

I want to download a file by pressing a button in my GUI, all works so that's okay. Offcourse my GUI locks up during the download. I tried some things like writing a thread and using gobject.idle_add. But none of these worked. Anyone can point me out to some kind of example or tutorial?

Totals in TreeView

Hi list, I try wit a different subject... sometime that makes the difference! I guess I'm not the only one that tried adding a different look for a row. In internet there's plenty of solutions via a model column and some via set_cell_data_func. I tried this but whet happens is that __all cell change color___ I tested with this code: http://dpaste.com/hold/81386/ and when the cell corresponding to "venice" gets colored, all tree cells get colored too. Any hints?

Treeview/ListStore and row_activated()

Hello, in my program I have a Treeview with a ListStore. I want to update a lable according to the row that is selected, and it works with row_activated(). The problem is that it needs to be double clicked. Is there a way that the program can see if the row selection has been changed with one click?

gtk.Table + Scrolledwindow with permanent headers?

Laszlo Nagy — 2008-09-27T05:33:34

I have a gtk.Table inside a scrolled window. I have many rows and columns in the Table. Each cell in the table contains a widget (typically a button, but not necessarily.) Some of the cells on the edges of the table are headers. They should always be visible even when the user scrolls in the middle of the Table. How can I achieve that? If this cannot be done with gtk.Table, can you please suggest another widget that can do the job for me? (If the cells cannot hold Widgets but can receive events then it may be a good solution...) Number of cells can be anything from 10 to 10 000.

No default icon in Treeview DnD using drag_begin

Jeffrey Barish — 2008-09-27T00:46:11

In the attached program, I get the default icon when I use enable_model_drag_source to enable the drag (set MANUAL to False). When I use drag_begin (set MANUAL to True), the icon is wrong. I need to use drag_begin so that I can disallow the drag under certain conditions. Thoughts?

Memory leak when using pangocairo for animation

Kyle Schaffrick — 2008-09-26T05:54:37

Greetings, I've isolated a fairly serious memory leak in an application I'm writing, which involves using pangocairo and cairo to draw text and graphics at moderately high update rates to produce an animated display. I managed to create the attached minimal script which reproduces the leak. It (the repro script) is kind of a hack, in that I'm using gtk.main_iteration() to turn the main loop inside out, but the problem originally/still appears when the drawing is initiated from timers in my normally arranged event-driven application. I have so far been unable to figure out what exactly is leaking (much less how to fix it), but it seems to be related to high turnover of of pango.Layout objects. I've tried using Python's GC debugging output and Valgrind leakcheck and didn't see any smoking guns, but I'm by no means a Valgrind wizard. For a long running process that does this type of drawing (such as an "realtime status display" sort of application, where I ran into this leak), the process will continue to grow until VM thrashing and/or OOM-killing occurs. With high-ish (16 Hz) update rates my Debian test system with 192MB of physical RAM is completely incapacitated by thrashing in a matter of 20-30 minutes or so. I've reproduced this on two disparate systems so far. Does this reproduce for anyone else, and/or does anyone see any obvious reason that this script would hemorrhage memory? I'm stumped :) -Kyle _______________________________________________ pygtk mailing list pygtk< at >daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

Cairo and Fonts

Jeffrey Drake — 2008-09-26T05:35:51

I would like to have a font to render some text, but able to do it from platform to platform. The platforms involved right now would be Windows and Linux, but with news of a gtk for osx, it may be extended to that. Is there a font that I can guarantee looks the same across all platforms, or could I actually distribute a font with the application to be loaded by cairo (outside of normal operating system fonts)? Another thing I am rather unaware of, is how to do it all with pygtk/cairo. Is there a decent example around that would help in this task? - Jeff. _______________________________________________ pygtk mailing list pygtk< at >daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
