Hi guys,
Do you have any idea if it would be feasible to enable gtkdialog to display an image from standard input (perhaps I'm not using this term correctly - see my explanation below)?
Here's a simple example of what I mean:
If a jpeg file has an exif thumbnail I can use the jhead command to extract this to a file. I can also extract it to standard output (-) like this `jhead -st - /24543.jpg`
So do you think it would be possible to enable the use of something like this?:
| Code: | <pixmap>
<input command>jhead -st - /24543.jpg</input>
</pixmap> |
Don't worry, I'm not thinking of writing a gtkdialog gui for all the command line image editors... although that would be interesting

Added hbox and vbox widgets scrolling capability
The hbox widget reference is available here.
The vbox widget reference is available here.
[EDIT] Updated 2011-06-25 12:31to support the width and height tag attributes to control the viewport dimensions.
Added hbox and vbox widgets scrolling capability via the "scrollable" custom tag attribute. If scrollable="true/yes/1" then the box is placed inside a GtkScrolledWindow.
Note that using width-request and/or height-request affect the hbox or vbox as you would expect, except that it's now inside a scrolled window. If you'd like to control the dimensions of the scrolled window viewport then there are two methods (at least) that you can implement: either use width-request and/or height-request in the parent widget or include width and/or height tag attributes in the scrollable hbox/vbox tag (this is consistent with existing widgets that are placed into GtkScrolledWindows - edit, list, table, tree - which use <width> and/or <height> directives to control their viewports, but as hboxes and vboxes are containers they don't support directives so we use tag attributes instead); the examples that follow illustrate this. I recommend placing scollable="true" in random hbox/vbox tags within a complex application to see the effect it has and the effect other widgets have upon it.
<hbox> widget example that controls the viewport dimensions through the parent widget:
| Code: | #!/bin/sh
# NOTE: This example requires at least gtkdialog-0.7.21 (please visit
# http://code.google.com/p/gtkdialog/). Additionally if you are using
# Puppy Linux then you may find that an historical version of gtkdialog
# already exists in /usr/sbin, and if that is the case then you should
# modify the shell variable below to point to the new gtkdialog binary.

Hi 01micko
When I first added the pixmap image refresh code I thought hmm, I could make a nice Yahtzee game now Are you posting yours somewhere?
I initially missed your post about playing my Pipepanic game but did see it on a later read through. I've also had thoughts about enabling events for pixmaps so that simple board games could be constructed

Thunor

Hi disciple.
It seems stdout from jhead can't be accepted. I suppose you know it works if you redirect to a file and point <pixmap> to that file, but not what you were hoping for.
~~~
thunor,
Yes dice roller is posted here. It's ugly but it works.
I also just posted a simple memory game in the same topic.
The new scroll functionality looks interesting, Many apps could benefit from this.
Cheers

Yes, I like to avoid using temporary files where possible.

Added comboboxtext widget
The widget reference is available here.
[EDIT] Updated 2011-07-02 14:21 to show the action and action type directives triggering for the default signal.
Added full action function type support which might've been overkill but I now know how to do it and can copy and paste my existing code to create new widgets.
I've managed the "changed" signal myself so that after initialisation you'll get one emission from any action function if the text has actually changed. The active="index" tag attribute gets applied after widget realization by GTK and it emits a "changed" signal itself.
The default directive will set the default based upon text, so there're two ways to set a default: by index or by text match.
Other things I've implemented are auto-selection of index 0 on initialisation which'll get overridden by the default directive or active tag attribute, auto-selection of the previous item (if possible) on deletion and the fileselect function inserts before the currently selected item. I made an effort to make this usable rather than just adding it and expecting application developers to work around it.
The entry version of this widget will follow after I've documented this one.
<comboboxtext> widget example:

Dear thunor,
Thanks a million. The glade problem is fixed! And the new combotext widget is great. I am now revising scripts to take advantage of it.
With kind regards,
vovchik

pixmaps |
|
Dear thunor,
I was thinking about disciple's request for a memory read and think it would not be too difficult to implement another type of input for <pixmap>:
| Code: | | <input memvar>$mypic</input> |
where mypic would be the result of a:
| Code: | | export mypic=`cat mypic.png` |
using gdk_pixbuf_new_from_data or gdk_pixbuf_new_from_inline (if converted to hexbytes first).
It's just an idea....
With kind regards,
vovchik
PS. I should have been more clear about the cat business. To avoid the newline and null byte problem with vars in bash, what about assuming a straight hex dump, e.g.: | Code: | | export mypic=`hexdump -ve '1/1 "%.2x"' mypic.png` |
and converting the dump for gdk_pixbuf_new_from_data. I have used gdk_pixbuf_new_from_data in different contexts and it works nicely.

Seems `gtk_widget_get_realized' isn't introduced until gtk+-2.20 so the latest revision fails to compile in Puppy-431. (gtk+-2.14)
Any work around possible?

It would be nice to see a work around, I agree... Hopefully the GTK version required will not climb too much, although I guess it will, as needs must..
