1. Syntax
The very basics of building a simple gui is told by the links in gtkdialog gtkdialog documentation. You should have played a bit with some examples before you continue.About QUOTES ( " and ' )
To show content of a variable in the gtkdialog code, we need to quote the variable correctly inside the gtkdialog code.
TEXT='Hello world' export script=' <text> <label>Content of variable is: '"$TEXT"'</label> </text>' gtkdialog --program=script
Now in other words - Because this is important!!!
First realize that you put all the gtkdialog code into a variable - ie MAIN_WINDOW or Psync:
export Psync="<window title=\"Psync\"...........</window>"
if you now try to echo Psync you'll get
<window title="Psync"...........</window>
which is correct code. But if you used ' instead of ", like this:
export Psync='<window title=\"Psync\"...........</window>'
you'll get
<window title=\"Psync\"...........</window>
This will give a syntax error, while
export Psync='<window title="Psync"...........</window>'
will give correct syntax.Now using a variable inside the gtkdialog code like this:
TITLE=Psync
export Psync="<window title=\"$TITLE\"...........</window>"
returns
<window title="Psync"...........</window>
while
export Psync='<window title="$TITLE"...........</window>'
returns
<window title="$TITLE"...........</window>
and not the content of variable TITLENow return to the first example about quotes. This example combines the use of ' and ".
