dcl tile attributes

[Tom]

How does one set the non-value attribute of a dcl tile from a lisp function? Getting them is easy, but not a word in help about setting them. Thanks in advance.

Every interactive tile takes and returns values as strings. To empty a tile (set_tile "TileKey" "").
Hope that's what you meant.

Thanks for the message, John. Perhaps I should have been clearer. I know set_tile can send a value to a tile, but how about the other attributes, e.g. the label attribute. Specifically, how would one set the label attribute of an edit box from a lisp function? Set_tile would only affect its value attribute. There must be a compliment to Get_attr with which one can pass an attribute from a tile to a function. Thanks again for your trouble.

To change a string in the dialog, ditch the 'Label', and use a 'text' tile: like so:

row {
text_25 { key = "msg1"; }
edit32_box { key = "edit_1"; allow_accept = true; }

}
In Lisp, do:
(setq msg1 "Italian phrase 1")
and, in dialog section, do:
(if (/= msg1 nil)(set_tile "msg1" msg1))

Bob is correct. You can't change the label attribute of a tile. If you have to enable/disable one [of the pair of tiles], then enable/disable both so they appear to be connected.

Another thing,
If you plan to change the 'text' value, it will not change until you (unload / load) the .dcl again. Can be done easily with Lisp, but causes a noticable 'screen-flicker' during repaint. No other way to do it that I know of.

By creating the dialog "on the fly" you could pass the label attribute as a variable when constructing the DCL file. Have a wee look here for an example :

There is a way to change the text of a label. It requires you to use ObjectDCL. ObjectDCL allows you to change the text of a label and allows you to do whole lot of other things, DCL just simply can't.

I suppose there is a way in ObjectDCL, but NOT in straight .dcl files. Using a 'text' tile rather than 'Label' will fix the problem.
