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 ( **{{color text=""" c="red"}}** and **{{color text="'" c="red"}}** ) To show content of a variable in the gtkdialog code, we need to quote the variable correctly inside the gtkdialog code. %%(language-ref) TEXT='Hello world' export script=' Content of variable is: '"$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 ##""MyGui""##: ~##export ""MyGui""=**{{color text=""" c="red"}}****{{color text=""" c="red"}}**## if you now try to ##echo ""MyGui""## you'll get ~#### which is correct code. But if you use **{{color text="'" c="red"}}** instead of **{{color text=""" c="red"}}**, like this: ~##export ""MyGui""=**{{color text="'" c="red"}}****{{color text="'" c="red"}}**## the value of ##""MyGui""## is ~#### This will give a syntax error, while ~##export ""MyGui""=''## will give correct syntax. Now using a variable inside the gtkdialog code like this: ~##TITLE="My title" ~export ""MyGui""=**{{color text=""" c="red"}}****{{color text=""" c="red"}}**## returns ~#### while ~##export ""MyGui""=**{{color text="'" c="red"}}****{{color text="'" c="red"}}**## returns ~#### and not the content of variable ##TITLE## Now return to the first example about quotes. This example combines the use of ' and ". ===@@**#%[[gtkdialogDocTips|❰❰❰ Previous]]#% #%[[gtkdialogDocTips|Index]]#% #%[[gtkdialogDocTips2|Next ❱❱❱]]#%**@@=== ---- ==Categories== CategoryGtkdialog
