<p>Unlikely.</p>
<ol>
<li>Geany does not know how wide the text entry is, you can resize the dialog and it grows/shrinks</li>
<li>Geany does not know how wide the displayed text is, its Unicode, so number of bytes != number of code points != number of glyphs and those can be varying widths depending on font and font size chosen</li>
</ol>
<p>So Geany would have to replicate most of the GTK layout code just to tell if the text exceeded the available width, pretty unlikely to happen, in fact (as best anyone can predict such things) won't ever happen unless its added to the text entry widget in GTK, sorry.</p>
