Hello everybody Iḿ trying to learn somethng about perl::GTK and I wrote some tiny code to do it. At this moment, I'm want to do an application capable to read permanently from /dev/ttyS0 and the output put into an entry box I'm using glade to draw the interface and (obviously) perl My temperature device is a temprax; this device send me the temperature readed from a probe trought a serial port in ascii format I can read from /dev/ttyS0 but I dont know how can I read continously from it and put the result in a entry Box T.I.A Tomás Wolfhack Vega Linux user #79917 at http://counter.li.org wolfh...@yahoo.com --- Free software is necessary for sustainable development.

Draw on a GtkFixed Widget with Cario and place some widgets inside?
Hi out there :) i have few questions i have to write a new tool for my work its something like a node based node editor so the nodes must be connect via splines and as content the node must have a tree view for the properties. So my first thought was to use GtkFixed get the drawable and draw something with cario on it and then place some treeviews widgets inside so do guys think it is possible? Concrete: 1) Can i draw on a GtkFixed with cario 2) Can i control the draw order from treeviews that the will draw after cario on the widget. I mean can i handle this with the realize signal and propagate it manual to the childs? without perm flushing? -- View this message in context: http://www.nabble.com/Draw-on-a-GtkFixed-Widget-with-Cario-and-place-some-widgets-inside--tp14421717p14421717.html Sent from the Gtk+ - Dev - General mailing list archive at Nabble.com. ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list

Re: GTK+ PopUp Window make it Transparent...
Good to know :) 1.Do u know how to get the HWND(is there a way to get the HWND from HGDIOBJ?) Its looks quit easy under win32: // Set WS_EX_LAYERED on this window SetWindowLong(hwnd, GWL_EXSTYLE, GetWindowLong(hwnd, GWL_EXSTYLE) | WS_EX_LAYERED); // Make this window 70% alpha SetLayeredWindowAttributes(hwnd, 0, (255 * 70) / 100, LWA_ALPHA); The problem is how to get this mechanism to GTK+ or better to cairo? Target function: cairo_set_source_rgba Is it possible to get the hwnd from cairo_t struct? Any advise will be helpfull cause i dont know where to start. regards.

Juhu got Alpha working :)
static gboolean expose(GtkWidget *widget, GdkEventExpose *event, gpointer
userdata)
{
cairo_t *cr = gdk_cairo_create(widget-window);
HWND hwnd = (HWND)gdk_win32_drawable_get_handle (widget-window);
SetWindowLong(hwnd, GWL_EXSTYLE,
GetWindowLong(hwnd, GWL_EXSTYLE) | WS_EX_LAYERED);
SetLayeredWindowAttributes(hwnd, 0, (255 * 70) / 100, LWA_ALPHA);
Have u an ICQ UIN?

Do u think that we can patch this small hack into GTK cause is very usefull
for GTK+Win32 user :)
