GtkDialog - tips

[fabrice_035]

Hi,

I think it's not possible, but question in case of

About button label

Code: Select all

<button>
<variable>okbutton</variable>
<label>"'`date`'"</label>
<action>refresh:okbutton</action>
</button>

The button take value only after load ? Update is not possible ?

Thx

The button take value only after load ? Update is not possible ?

Labels are fixed even before gtkdialog starts.

You could try a work around with an updated button icon:

Code: Select all

#!/bin/bash
update_icon () {
echo '<''svg width="100" height="20"><text x="50%" y="70%" text-anchor="middle">'"$(date +%T)"'</text></svg>' > /tmp/buticon.svg
}; export -f update_icon

update_icon
echo '
<button>
	<variable>BUT</variable>
	<input file>/tmp/buticon.svg</input>
	<action>echo do something useful here</action>
	<action>update_icon</action>
	<action>refresh:BUT</action>
</button>
'|gtkdialog -s
rm /tmp/buticon.svg

@MochiMoppel : whaouu, very nice! Respect

Dear Mochi,

Brilliant. And thanks for the example. We can also make it pretty without much effort:

Code: Select all

#!/bin/bash

function update_icon() 
{
echo '<''svg width="300" height="60">' \
		'<rect x="1%" y="1%" rx="5%" ry="10%" width="98%" ' \
		'height="98%" fill="darkorange" stroke="darkred" ' \
		'stroke-width="3.5"/> <text x="50%" ' \
		'stroke="darkred" stroke-opacity="1.0" stroke-width="2.4" ' \
		'fill="white" fill-opacity="1.0" font-weight="800" ' \
		'font-size="50" font-family="Sans" ' \
		'y="78%" text-anchor="middle">'"$(date +%T)"'' \
		'</text></svg>' > /tmp/buticon.svg
}

export -f update_icon
update_icon

echo '
<button>
   <variable>BUT</variable>
   <input file>/tmp/buticon.svg</input>
   <action>echo "Do something useful here..."</action>
   <action>update_icon</action>
   <action>refresh:BUT</action>
</button>
'|gtkdialog -s

rm /tmp/buticon.svg

With kind regards,

@vovchik : terrrrrible

I not understand functions on timer widget
http://01micko.com/reference/timer.html

Code: Select all

<timer tag_attr="value"...>
	<variable>varname</variable>
	<input>command</input>
	<input file>filename</input>
	<sensitive>state</sensitive>
	<action>activity</action>...
	<action signal="type">activity</action>...
	<action function="type">parameter</action>...
</timer>

I try the "input file" activity, never working
I imagine when the input file change then action signal receive a signal ?

example

Code: Select all

#!/bin/bash

touch /tmp/myfile

echo '
<button>
   <variable>BUT</variable>
   <label>press me</label>
   <action>echo "button down"</action>
   </button>
   
   <timer visible="true" milliseconds="true" file-monitor="true">
   <input file>/tmp/myfile</input>
   <action>echo "working signal"</action>
   </timer> 

'| gtkdialog -s

So, if i change /tmp/myfile with echo "xxx" > /tmp/myfile
There is no signal transmitted

Explain me please.

[MochiMoppel]

I made small changes to your example. Every time the button is pressed, the file /tmp/myfile is updated.
The timer widget monitors this file and, when the file changed, emits a "file-changed" signal. I have no idea why the signal is emitted twice.

IMO using the timer widget in this way makes little sense.
Interesting detail: The widget allows more than one input file. Add an <input file> tag for each file and the timer widget will emit a signal when any of these files change.

Code: Select all

#!/bin/bash
touch /tmp/myfile
echo ' 
 <button> 
    <variable>BUT</variable> 
    <label>press me</label> 
    <action>date > /tmp/myfile</action> 
 </button> 
     
 <timer visible="true" milliseconds="true" file-monitor="true"> 
    <input file>/tmp/myfile</input> 
    <action signal="file-changed">echo "working signal"</action> 
 </timer> 
 '| gtkdialog -s

[fabrice_035]

Again thank you MochiMoppel.

And I propose this to answer the question of Argolance.
what do you think about it?

Code: Select all

#!/bin/bash
# 

touch /tmp/enable_button
touch /tmp/disable_button

# rem 

myscript () {

echo "script execute until end and disable button, user must wait"

echo 0 > /tmp/disable_button
#...
sleep 5
#...
echo 0 > /tmp/enable_button
echo "enable now!"

} ; export -f myscript 

echo '
 <button>
    <variable>BUT</variable>
	<label> START </label>
    <action>myscript&</action>
 </button>
     
 <timer visible="true" milliseconds="true" file-monitor="true" >
   <input file>/tmp/disable_button</input>
   <action signal="file-changed">disable:BUT</action>
 </timer>
 
  <timer visible="true" milliseconds="true" file-monitor="true" >
   <input file>/tmp/enable_button</input>
   <action signal="file-changed">enable:BUT</action>
 </timer>

 '| gtkdialog -s

[MochiMoppel]

Methinks that it will not work.
And since Argolances's question was asked in a different thread you should link to his question or better post in his thread.

[fabrice_035]

Perhaps. But i think it's the only way to activate and/or desactivate button while waiting for the end of a script. But i am not expert! Regard.

[Argolance]

Bonsoir,
Is it possible to execute a command when a combobox widget is clicked to select an item in the list (for example to echo some message to any temporary file)? If yes, how?

Code: Select all

<combobox>
 <variable>COMBOBOX</variable>
 <item>First item</item>
 <item>Second item</item>
 <item>Third item</item>
 <action>echo yes > /tmp/tmpfile</action>
</combobox>

Thank you.

Cordialement.

[fabrice_035]

@Argolance,

I search too, i think it's not possible.

I tried that with comboboxtext

https://github.com/oshazard/gtkdialog/b ... us/signals

key event work, not mouse activity.

Of course changed event work

Code: Select all

<action signal="changed">echo changed item!</action>

while waiting for an expert

Bonne soirée.

Looking at docs
http://01micko.com/reference/combobox.html

Various action signals are mentioned.

http://01micko.com/reference/combobox.html

Code: Select all

The following signals are connected-up for all widgets:
button-press-event, button-release-event, configure-event, enter-notify-event, leave-notify-event, focus-in-event, focus-out-event, hide, show, realize, key-press-event, key-release-event, map-event, unmap-event

I think is wrong, u can try.

I hope I'm wrong.

I had a look to this page which is in my favorites... but I make the same observation as fabrice_035 (que je salue au passage! ): I didn't get any results!
On the other hand, this works as expected for me with the comboboxtext:

Code: Select all

<action signal="changed">echo changed item!</action>

... that I discover and is much better in my case, because this kind of combobox prevents user to alter or type some wrong item in the entry. The option value-in-list seems to be instable and to make the script freezing in some cases.
Thanks!

[MochiMoppel]

I'm afraid you are right.
May depend on what "connected-up" is supposed to mean. Things can be connected but not working (my laptop battery ). There is hardly any widget for which all signals in the list work, but combobox, comboboxtext and comboboxentry are an extreme. Only key-press-event and key-release-event seem to work.

Hi,

The source code can teach us a few things

Example about combobox, open widget_combobox.c, and go to line 223

Code: Select all

		/* Connect signals */

It's empty!

Compare with widget_comboboxtext.c (line 487)

Code: Select all

/* Connect signals */
		g_signal_connect(G_OBJECT(var->Widget), "changed", 
			G_CALLBACK(on_any_widget_changed_event),
			(gpointer)var->Attributes);
(...)

I wanted to copy the behavior of wigget_button.c to -> widget_comboboxtext.c but

Code: Select all

(gtkdialog:30539): GLib-GObject-WARNING **: /build/buildd/glib2.0-2.40.2/./gobject/gsignal.c:2462: signal 'toggled' is invalid for instance '0x916d918' of type 'GtkComboBox'

Which is curious https://github.com/oshazard/gtkdialog/b ... /ChangeLog read changelog:

Code: Select all

* Thu Nov 1 2012 Thunor <thunorsif@hotmail.com>
- Connected-up the button-press/release-event signals to the
comboboxentry widget's child entry widget.

It's important -> *widget's child entry widget* <-

Comboboxtext and comboboxentry *are the same* widget (there is no source code for comboboxentry https://github.com/oshazard/gtkdialog/tree/master/src

widget_comboboxtext.c :

Code: Select all

g_signal_connect(G_OBJECT(gtk_bin_get_child(
				GTK_BIN(var->Widget))), "button-press-event",
				G_CALLBACK(on_any_widget_button_pressed),
				(gpointer)var->Attributes);
			g_signal_connect(G_OBJECT(gtk_bin_get_child(
				GTK_BIN(var->Widget))), "button-release-event",
				G_CALLBACK(on_any_widget_button_released),
				(gpointer)var->Attributes);

I think the window decoration is not tested but just the inside text.

Bonsoir,
Bon, là, on joue plus dans la même cour!
Effectivement ça marche mais j'avoue être perso "somewhat" largué, eh eh, sur la façon de parvenir à un tel résultat, ah ah...
Well done and thanks .

Bonjour,

FILE="`cat /tmp/checkbox_test`"

for LINE in $FILE; do
LIST="${LIST}

		<default>true</default>
		<label>$LINE</label>
		<action>if false disable:$LINE</action>
		<action>sed -i 's/$LINE//' /tmp/checkbox_test</action>

I=$IFS; IFS=""
for STATEMENTS in  $(gtkdialog --program=MAIN); do
   eval $STATEMENTS
done
IFS=$I

[ "$EXIT" = "restart" ] && $0

In this script, I can't find the solution so that the sentence containing spaces is not segmented.
I tried a lot of things by manipulating single and double quotes, escaping spaces, etc... but without success!
Any idea?
