Re: GtkLabel + PangoLayout

["Leonel Freire" <leonelfreire gmail com>]

I'm was trying to change de label pango context matrix, but no success.

"because you need to queue a redraw of the label."

After this I wrote...

...

layout = gtk_label_get_layout(GTK_LABEL(label));
pango_layout_set_text(layout, "TEXT", -1);

gtk_widget_queue_draw(label);

But nothing happened...

The only way that I found was setting a callback (expose-event) for the label....

But my problem is: I must do (emule) a printer, just a widget showing lines (like a paper) with a scroll. The printer receives some commands to change the mode, like normal font, double height font and double width font. If I have 42 cols and my char is 10x20 (pixels) then:

Normal font: 42 chars, (420 x 20) -> one normal line
Double height: 42 chars (420 x 40) -> two lines for each char, but the same width
Double width: 42 chars (210 x 20) -> two "char width" for each char, but the same height

There's no way to set the font height ou width with pango, just the size, in points, so I was trying to use the transformation matrix (PangoMatrix) and setting it to the context, but I had a lot of problems. =\

Can you (or someone) think in a better way to do this? =|
