Using the flagged property in a field
The flagged property allows you to highlight a run of characters with a red dotted underline. This is particularly useful for highlighting mistakes.
The sample stack
Create a stack and add a field, name the field "display".
Add some text to the field, in this example I have used the first paragraph of Alice in Wonderland, and have deliberately misspelled some of the words.
Flagging a piece of text using a chunk expression
You can use a chunk expression to flag any piece of text.
In this example the word 'begining' is misspelled so we want to flag it. It is the 3rd word of the field so you can run this in the message box:
set the flagged of word 3 of field "display" to true
You can use any chunk expression so you can flag lines, ranges of text, for example
set the flagged of line 1 of field "display" to true set the flagged of word 3 to -1 of line 2 of field "display" to true
You could run this in the card script, using
on openCard set the flagged of line 1 of field "display" to true end openCard
Now if you close the stack and open it again, the first line will be flagged.
Flagging the selection
You can also flag, or unflag the current selection using the selectedChunk function.
Add two buttons to the stack, one to flag the selection and one to unflag the selection.
The script of the "Flag Selection" button is
on mouseUp set the flagged of the selectedChunk to true end mouseUp
The script of the "Unflag Selection" button is
on mouseUp set the flagged of the selectedChunk to false end mouseUp
Now highlight a piece of text and click the "Flag Selection" button.
