Gtkdialog Development

[disciple]

Maybe there's something I'm missing about what you're asking, but Argolance's example I linked to is for a tree widget. Argolance was looking for help because it had a problem if you clicked on an item and didn't drag it, and 8-bit posted a link to a workaround for that problem using getcurpos http://www.murga-linux.com/puppy/viewto ... 651#549651

[disciple]

Ah, sorry - you haven't edited your last post, have you?
I thought you said you were not talking about your example of moving items in a list widget. But you didn't say that - I must have imagined it.

Maybe there's something I'm missing about what you're asking

I think I was missing this bit:

using gtk-options

8-bit's example does not use gtk-options. Unless I'm misunderstanding what "gtk-options" means, of course.

...moving items inside a <tree> widget...using gtk-options.

The GTK+ property is "reorderable".

[seaside]

Ah yes, "reorderable".

I think this operation needs a tooltip to go with it. I remember struggling with trying to move an item up and down a list and constantly ending up with placing it as a subheading instead.

The trick is after highlighting an item, drag it to the right and keeping the mouse button down move the item up and down and watch for a line under the item where you wish it placed.

Hi seaside

I researched this a while back and I couldn't stop the branches from appearing when dragging-and-dropping onto existing rows. What I discovered was that Gtkdialog's tree widget is a GtkTreeView using the GtkTreeStore model which is "a tree-like data structure", whereas -- I'm assuming as I haven't tested it yet -- a GtkTreeView using the GtkListStore model implementing "a list-like data structure" may have been more appropriate. Maybe there was a reason why the tree-like structure was chosen over the list-like structure.

Added timer widget

The widget reference is available here.

• The default signal is "tick", emitted when the timer ticks.
• The default precision is seconds and the default interval is 1s.
• Use the milliseconds="true/yes/1" custom tag attribute to use milliseconds.
• Use the interval="value" custom tag attribute to set the interval (unsigned integer).
• Use the tag attribute (GTK+ property) visible="false" to hide the timer.
• Disabling the timer pauses it, enabling the timer unpauses it.

The timer is created enabled by default, but if you want it disabled then use the <sensitive>false</sensitive> directive or the sensitive="false" tag attribute.

The timer itself doesn't affect CPU usage (I tested with 255x1s timers) but what the application developer executes on the "tick" signal will.

<timer> widget example:

Code: Select all

#!/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.

I tried to compile the latest but it seems to have a problem, I don't really know much about this so it could be me.

Here is what I get after running make.

Code: Select all

widget_timer.o: In function `widget_timer_timer_callback':
/root/gtkdialog/src/widget_timer.c:379: undefined reference to `gtk_widget_get_sensitive'
widget_timer.o: In function `widget_timer_envvar_construct':
/root/gtkdialog/src/widget_timer.c:137: undefined reference to `gtk_widget_get_sensitive'
collect2: ld returned 1 exit status
make[3]: *** [gtkdialog] Error 1

make[2]: Leaving directory `/root/gtkdialog/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/gtkdialog'
make: *** [all] Error 2

The previous version worked fine for me, seems to be the timer widget is the problem.

Working ok in Slacko-312.37

Don't you use quirky-NOP Geoffrey? gtk+ version is old in that.

Yeah, quirky 1.20 NOP, strange though it has worked ok up until now, I may have reached it's limitations, not to worry
I should look at using a newer version of puppy, It's just that I prefer xfce as a window manager.

Ah, that's cool.

An interesting point is that neither method works after you sort the tree by clicking on a column header.

Hi Geoffrey

Sorry about that. gtk_widget_get_sensitive requires GTK+ 2.18.0 and I missed it, but thanks for letting me know as there is an older alternative which I've included and committed

Interestingly its sister function gtk_widget_set_sensitive already exists within the project and has no version requirements.

I don't have the very latest gtkdialog here, but I'm guessing this isn't fixed yet:

sunburnt:
Here's a program written in two ways to show the different options.


Secondly --event-driven=filename

Code: Select all

#!/usr/sbin/gtkdialog3 -e
display(){ echo "Display: ${!1}"; }
...............

Just wanted to add that using the "#!/usr/sbin/gtkdialog3" event form requires that gtkdialog3 is symlinked to gtkdialog, otherwise it errs. I ran into this earlier using the "event driven" form of gtkdialog - no matter from a file or on the command line.

Potong, thanks for supplying all this great information on Gtkdialog. It is immensely helpful.

Regards,
s

Can anyone confirm?

[disciple]

In other words, if the executable is named something other than "gtkdialog", then you need to create a link to it named "gtkdialog", to be able to use the event-driven option.

Well it's fixed now The "gtkdialog" binary name was hardcoded.

The badly named <visible>disabled </visible> directive has been deprecated in favour of <sensitive>false/no/0</sensitive> which is what it actually is. I'm going to remove <visible> from the wiki so that folk don't use it anymore.

Hi thunor,

Is there no way to add a filter to gtk-open "fileselect" for specific filetypes?
This would really be a huge plus gtkdialog3. Thanks

Overhauled the notebook widget

The widget reference is available here.

• The page number is now stored within the variable and can be refreshed from a command or a file.
• Tab labels can be specified with the "tab-labels" custom tag attribute.
• Tab labels can be generated automatically by using either or both of the "tab-prefix" and "tab-suffix" custom tag attributes.
• Tab labels will be generated automatically using "Page n" in the absence of any of the above custom tag attributes.
• The "tab-base-index" custom tag attribute can be used to control the start page number used within the auto-generated labels.

This widget does not accept setting a default page before being shown (there's a note about it here) which will result in <input> and <input file> data being discarded at start-up. This issue can be overcome by using the "page" tag attribute which will be applied after the widget is shown.

<notebook> widget example:

Code: Select all

#!/bin/sh
