The following script shows something I do not understand. It seems that if I have, on a VID screen, a "text" item, I can not change its value unless it had some value to start with. I have gotten around the problem by putting default values in text items, so I am not having a "problem," but it's not quite the way I imagined things should work. Is there a bug, or am I imagining wrong? In the following script, if you click the "show text" button, it will refresh the text of three text items, and then show them, but the only one that will show anything is TEXT-3, the one that had some default text there in the first place. Thank you. REBOL [ Title: "Test text item" ] SHOW-TEXT: does [ TEXT-1/text: "text one" TEXT-2/text: "text two" TEXT-3/text: "text three" show [ TEXT-1 TEXT-2 TEXT-3 ] ] view layout [ across label "TEXT-1" TEXT-1: text "" return label "TEXT-2" TEXT-2: text " " return label "TEXT-3" TEXT-3: text "default text" return button "Show text" [SHOW-TEXT] ]
It's a feature. Try this instead if you want to see your changes Code: view layout [ across label "TEXT-1" TEXT-1: text "" 40 return label "TEXT-2" TEXT-2: text " " return label "TEXT-3" TEXT-3: text "default text" return button "Show text" [SHOW-TEXT] ]
Yes, text item is not flexible. When you decide the length, it will remain forever. So a " " can't show quite anything! Moreover there is extra spaces suppression in text string, so there is no differences between Code: "" and Code: " " The most elegant solution is to provide the maximum length like: Code: TEXT-1: text "" 40
