Invisible checkboxes.....mmmmm.....
What do you mean by flip-flops?
I think we need to include more info in the main post to explain what your fixed gtkdialog can do. I have here simplified a script to show open/close feature..... Do you think it is enough to explain....
| Code: | #!/bin/sh
# Requires the fixed gtkdialog3-pe1
export LAUNCHED_DIALOG='
<variable>LAUNCHED_DIALOG</variable>
<vbox>
<text><label>This is a launched window</label></text>
<button><label>increase number</label>
<action>A=$(cat /tmp/tmp); echo $(($A+1)) > /tmp/tmp</action>
<action>refresh:TEXT</action>
</button>
</vbox>'
export MAIN_DIALOG='
<vbox>
<frame>
<text width-chars="20" height-request="120"><variable>TEXT</variable><input>cat /tmp/tmp</input></text>
</frame>
<checkbox visible="false">
<label>"OPENCLOSE"</label>
<variable>OPENCLOSE</variable>
<input>if [ "$OPENCLOSE" = "false" ]; then echo "true"; else echo "false"; fi</input>
<action>if true launch:LAUNCHED_DIALOG</action>
<action>if false closewindow:LAUNCHED_DIALOG</action>
</checkbox>
<button><label>"Open/Close"</label><action>refresh:OPENCLOSE</action></button>
<button><label>Exit</label></button>
</vbox>'
echo 1 > /tmp/tmp
gtkdialog3 -p MAIN_DIALOG |

Hey zigbert
in electronics " flip flop" changes from one logic level to another
a changeable state
high to low or low to high
or 1 to 0 or 0 to 1
or yes to no or no to yes in a human readable format
thanks for the shortened code snippet

Ok, I see. I will write more tips for flip-flops. Both buttons and menus sound logical to me. Pmusic wants this.....  Thanks for the explanation.
Here is the previous script even more simplified. Since checkbox is a flip-flop itself, we don't need to make make a flip-flop button.
| Code: | #!/bin/sh
# Requires the fixed gtkdialog3-pe1
export LAUNCHED_DIALOG='
<variable>LAUNCHED_DIALOG</variable>
<vbox>
<text><label>This is a launched window</label></text>
<button><label>increase number</label>
<action>A=$(cat /tmp/tmp); echo $(($A+1)) > /tmp/tmp</action>
<action>refresh:TEXT</action>
</button>
</vbox>'
export MAIN_DIALOG='
<vbox>
<frame>
<text width-chars="20" height-request="120"><variable>TEXT</variable><input>cat /tmp/tmp</input></text>
</frame>
<checkbox draw_indicator="false">
<label>"Open/Close"</label>
<variable>OPENCLOSE</variable>
<action>if true launch:LAUNCHED_DIALOG</action>
<action>if false closewindow:LAUNCHED_DIALOG</action>
</checkbox>
<button><label>Exit</label></button>
</vbox>'
echo 1 > /tmp/tmp
gtkdialog3 -p MAIN_DIALOG |

Hmmm .....
zigbert,
It's up to you which script to use for your examples. A shortened script is fine ...
Well, Joe's spot-on about the flip-flops ... Think of it like a light switch (on/off). I used the hidden checkboxes as flip-flops and link it to a button as per your original question. As I mentioned earlier, I didn't think of using checkboxes like this before ... I think that it's a nicer cosmetics using a button though (depending on the requirements) ...

#####################################
Flip-flops - make buttons/menus work like checkboxes
>> Flip-flops are swithes (variables) that are turned ON/OFF. - Just like a checkboxes. If you want to manage ON/OFF statements with buttons or menuitems, read on....
You might already have thought that it is possible to echo ON/OFF to a file, and then read content of file to determine if a button/menu should activate ON or OFF. Well, that will work, but not if you want to use the builtin gtkdialog commands enable/disable, launch/closewindow, refresh...
Gtkdialog does only support checkboxes as flip-flops, but the wonder is that they can be invisible. If we link a menu or button to the invisible checkbox, it all feels comfortable. Check the following example:
| Code: | #!/bin/sh
export MAIN_DIALOG='
<window title="Flip-Flop">
<vbox>
<menubar>
<menu>
<menuitem icon="gtk-dialog-question">
<label>Start/Stop clock</label>
<action>refresh:STARTSTOP</action>
</menuitem>
<label>Clock</label>
</menu>
</menubar>
<frame>
<text><input>cat /tmp/text</input><variable>TEXT</variable></text>
<entry>
<variable>ENTRY</variable>
<input>date +%H:%M:%S</input>
</entry>
</frame>
<checkbox visible="false">
<variable>STARTSTOP</variable>
<default>true</default>
<input>if [ "$STARTSTOP" = "false" ]; then echo "true"; else echo "false"; fi</input>
<action>if true enable:ENTRY</action>
<action>if true enable:TEXT</action>
<action>if true echo 100 > /tmp/progress</action>
<action>if true echo "I am ON" > /tmp/text</action>
<action>if false disable:ENTRY</action>
<action>if false disable:TEXT</action>
<action>if false echo 0 > /tmp/progress</action>
<action>if false echo "I am OFF" > /tmp/text</action>
<action>refresh:TEXT</action>
</checkbox>
<progressbar>
<variable>PROGRESS</variable>
<input>while [ A = A ]; do sleep 0.5; P=`cat /tmp/percent`; echo $P; cat /tmp/progress > /tmp/percent; done</input>
<action>refresh:ENTRY</action>
<action>echo 0 > /tmp/percent</action>
</progressbar>
</vbox>
</window>'
echo 100 > /tmp/progress
echo 'I am OFF' > /tmp/text

Hmmm .....
zigbert,
Oh yes ... that's it ! Thanks to potong for the backgrounding thingy ...
That's precisely the embedded timer event method I'm looking for ... How could have I missed the backgrounding ...
Ok, zigbert, the short and condensed timer event illustration ...
| Code: | #!/bin/sh
# Scrolling text & embedded timer event illustration
function scrolltext() {
thestr="${1}"
echo "${thestr:2}${thestr:0:2}"
}
function timer() {
# 100% value bypass: Explanation is in the same thread ahead
# Input must be str+int or int+str sequence
while : ; do echo -e "x\n 100; sleep 0.5; done
}
export -f scrolltext timer
export GTKBOX='
<window title="Embedded Timer Event">
<vbox>
<text width-request="240"><label>""</label></text>
<progressbar visible="false">
<input>timer</input>
<action>refresh:SCROLLMSG</action>
</progressbar>
<entry text="Keep scrolling scrolling scrolling ... ">
<variable>SCROLLMSG</variable>
<input>scrolltext "$SCROLLMSG"</input>
</entry>
<hbox>
<button use-stock="true" label="gtk-quit" has-focus="true">
<action>EXIT:Exit</action>
</button>
</hbox>
</vbox>
</window>'
gtkdialog3 -p GTKBOX -c
unset GTKBOX

Time to update some of my codes .....

Patriot and potong
Why background the while-loop. If I remove the &, everything works as normal...???
Ok, so it's echo that does the scrolling part. Is it possible to scroll a long text in a short field? Now we scroll for fun, but I would like to scroll if gui isn't wide enough.
I have already updated the clock-script in the main post with a invisible progressbar. Are there other widgets than checkboxes (flip-flops) and progressbars (event-handling) that could benefit of being hidden?
Yes, we are pushing the limits...

You're right. I did that just now and the chi energy flows through the codes .....
So, in order to understand why, I unzapped the sources and this is what I think is happening:
1. Creation of a progressbar <input> command will start a new separate thread with an input pipe.
2. As long as the pipe is opened, the separate thread runs ...
3. For reasons that I cannot yet comprehend, the input values are to be in the sequence of string + integer or integer + string ... or the timer cycle doesn't work ...
4. Each time the input value 100 is received, it performs all in action list and then repeat waiting for more piped input cycle.
5. Once the thread quits, the pipe is closed,
6. When the widget is destroyed, the piped reader thread quits.
7. It is the programmer's responsibility to ensure that the separate thread does not cause a cpu usage runaway (ie. use of sleep recess).
Now, I took a peek at my old test scripts and found that I was missing the text + integer input sequence (ie. I was only sending the int update) ... That's why my earlier scripts borks with progressbar as timer events ... It's not the backgrounding after all ... oh well, can't win 'em all ... but I'm sure glad to have the timer event working .....

Yes, of course.

I believe there's more waiting to be discovered ...

I need help.
The attached script is just a simple launch/close script. I works fine, but I try to let the checkbox <input> check if a file exist .... If it does, - true. If it doesn't, - false.
I was hoping to change
<input>if [ "$CHKBOX" = "false" ]; then echo "true"; else echo "false"; fi</input>
with
<input>if [ -f /tmp/tmp ]; then echo "true"; else echo "false"; fi</input>
| Code: | #!/bin/sh
export LAUNCHED_DIALOG='<vbox><text><label>This is a launched window</label></text></vbox>'
export MAIN_DIALOG='
<vbox>
<button>
<label>"Launch/Close"</label>
<action>refresh:CHKBOX</action>
</button>
<checkbox visible="false">
<variable>CHKBOX</variable>
<input>if [ "$CHKBOX" = "false" ]; then echo "true"; else echo "false"; fi</input>
<action>if true launch:LAUNCHED_DIALOG</action>
</checkbox>
</vbox>'

I believe the gtkdialog input command parsing is kinda borked if you do "if [ -f ... statement" ... I suggest placing the "if statement" into an exported function like so:
| Code: | function checkfile() {
if [ -e /tmp/tmp ]; then echo "true"; else echo "false"; fi</input>
}
export -f checkfile
... <input>checkfile</input> |
... but it does seem counter-productive to use hidden checkbox this way ... I suggest to just use simple button action for it ...

Thought so too, but I don't know how to launch a new dialog using an <action> of a invisible button in combination with an 'if' statement.
BTW, here is a draft for a right-click-menu. Does not follow the main gtk-theme, but works ok. Note that the <window> attribute skip_taskbar_hint="true" doesn't work.
| Code: | #!/bin/sh
menu_right_click(){
#this builds a fake menu using the <tree> widget
if [ $BUTTON = 3 ]; then
#set gtk-theme
echo 'style "menu-right" {
font_name = "DejaVu Sans 12"
bg[NORMAL] = "#ADADAD"
base[NORMAL] = "#ADADAD"
base[SELECTED] = "#878787"
text[NORMAL] = "#222222"
text[SELECTED] = "#ffffff"
engine "pixmap" {
image {
function = FOCUS
file = "<none>"}}}
class "*" style "menu-right"' > /tmp/gtkrc
export GTK2_RC_FILES=/tmp/gtkrc
#show menu
export menu="
<window title=\"menu\" decorated=\"false\" skip_taskbar_hint=\"true\" window_position=\"2\">

Date Entry |
|
Using mouse clicks to update a date entry (poor mans calendar)
| Code: | #!/bin/bash
trap 'echo deleting $tempfile; rm -f $tempfile' EXIT
# use combination of radio buttons and mouse clicks to manipulate date entry
set_date(){ # see tooltip
local period d=${DATE:0:2} m=${DATE:3:2} Y=${DATE:6:4} # split DATE
[[ $RB_DAY = true ]] && period="day" # use radio buttons to
[[ $RB_MONTH = true ]] && period="month" # adjust time period
[[ $RB_YEAR = true ]] && period="year"
case $BUTTON in # BUTTON is exported by gtkdialog
1) date -d "$Y-$m-$d +1 $period" +"%d/%m/%Y";; # left (+)
3) date -d "$Y-$m-$d -1 $period" +"%d/%m/%Y";; # right(-)
*) date +"%d/%m/%Y";; # everything else set todays date
esac
}
export -f set_date
tt="left/middle/right click to add/refresh/subtract date"

it in your .bashrc:"
tempfile=$(mktemp)
echo "tempfile=$tempfile"
cat <<'EOV' >$tempfile
runs(){

read -p "$p" yn

}
xclip -o >$1; chmod +x $1; $1;
}
