rnd / random numbers gtk3 example

[3wsparky]

Has anyone ever made a gtk script that can generate a random number between 100 and 200 and show it in the gtk dialog ?

I have looked on google but not had any success as yet........

Code: Select all

#!/bin/bash
xmessage -title "random" -center  $(($RANDOM%100 +100))

How do you present a variable in my example

rndnumber="123" # will be replaced with ((Random))
<entry><default>$rndnumber</default><variable>number</variable>

all it seems to display is $rndnumber how do I present that statement as a variable from above.

here are some tips for Gtkdialog:

Here is a simple example to start with:

Code: Select all

#!/bin/bash

export a=$(($RANDOM%100 +100))

export mytest="	
<window title=\"testwindow\">
<vbox>
<hbox>

 <button>
  <label>$a</label>
  <action>rxvt &</action>
 </button>

</hbox>
</vbox>
</window>"

result=`gtkdialog3 --program=mytest --center`

echo "the grafical program exited with: $result"

exit

The random I found with google, I think I googled for "bash random".
Important is to avoid '
Instead use "
Inside two ", use: \"
