How can overflow be automatically displayed when a text box is moved into the layout?

[dublove]

After moving horizontally into the layout, if sb[2] exceeds the bottom edge, overflow is displayed.
This is instead of expanding, as the text may be very long.

sel[j].visibleBounds = [sb[0], lcb, sb[2], rcb];

What's your question @dublove ?

[dublove]

I am researching text box adaptation columns, but the text box is too long, and I don't want it to exceed the page layout.

So what's your question?

You don’t know how much content is oveflowing, so you would have to fit the frame to the content

app.activeDocument.selection[0].fit(FitOptions.FRAME_TO_CONTENT)

[dublove]

After FitOptions.FRAME_TO_CONTENT, the text box will exceed the page margin.

I want the textFrame display a red “+” with the text “overflow text” when the sb[2]  exceeds the bottom edge.

I don't know what mechanism causes it to go all the way to the bottom of the interface.
Is it possible to stop the expansion at the bottom of the page?

This seems feasible:

var pb = sel[j].parentPage.bounds;
var bm = pp.marginPreferences.bottom.
. . . . . .
sel[j].visibleBounds = [sb[0], lcb, pb[2] - bm, rcb];
sel[j].fit(FitOptions.FILL_PROPORTIONALLY);

//sel[j].fit(FitOptions.FRAME_TO_CONTENT);
