Is there any way to display HTML in a GTK-PHP app? If not, are there any plans to embed Gecko or something?
Thanks,
Kees |

Kees, you can use basic markup when using Pango, e.g. in a label.
See http://php-gtk2.de/manual/en/html/gtk/gtk.gtkmessagedialog.constructor.html for an example. Remember that GtkLabel is only for short (single line) text, not for whole pages. When you want to display more text, you should use GtkTextView (which has a similar Model-View concept as GtkTreeView).
Displaying full HTML pages is not possible. For this you would need a php-gtk2 module called "mozembed", but as php-gtk2 is not even beta right now, we are concentrating on the basic things. Extra modules come when php-gtk2 is stable. |

Fair enough. I am trying to write a tool that generates cross tabulations, it would be nice when the resulting tables can be displayed in HTML.
Otherwise, thanks and keep up the good work!

I don't want to step on your toes, Christian, but I discovered that multi-line labels are possible using "\n" or "\012" in the label's text string. A lot of other escape sequences are also available for doing such things as typographic quotes, copyright symbols, etc.
Also, even though labels aren't really designed for multi-line text display, if the text is going to be read-only, pango might be enough, depending on how elaborate Kees wants to get.
If anyone is interested, I can post a list of usable escape sequences for PHP-Gtk2.

It is possible, but shouldn't be used for longer texts. Because it's not made for that. |

Is there a memory consumption issue involved? I'm just wondering why this should be avoided.

GtkLabel has not been designed to display large amounts of text. It will scale very bad when you try to do this, and take too much cpu and stuff. Don't ask me for details, I just repeat what I've heard :) |

Hi,
I couldn't get this to run:
$lab = new GtkLabel(null);
$lab->set_markup('<table><tr><td>bla</td><td>bla</td></tr><tr><td>bla</td><td>bla</td></tr></table>');
I suppose it's because of the table? Other stuff (<b>,<i>) indeed works fine. Where can I find the markup that is supported? Can't find anything on the Pango website...
Thanks,
Kees |

Thanks for clearing that up, Kees.
