1. [IUP] IupText minimum size [SOLVED]

I am trying to make the text field auto-expand when the window is resized. If I start with a size of 100x100 then it works pretty much as I want (apart from being the wrong size and place), however if I start with a size of 800x100 then it seems to set a minimum size on the text field that it will not shrink below, so the X is clipped below 800. Any ideas?
(include pGUI.e) Ihandle flbl, ftxt, flb2, box, dlg IupOpen() flbl = IupLabel("Filter") ftxt = IupText("") IupSetAttribute(ftxt, "EXPAND", "HORIZONTAL") flb2 = IupLabel("X") box = IupHbox({flbl,ftxt,flb2}) IupSetAttribute(box, "MARGIN", "2x2") IupSetAttribute(box, "GAP", "10") dlg = IupDialog(box) IupSetAttribute(dlg, "TITLE", "pdemo") IupSetAttribute(dlg, "SIZE", "100x100") -- IupSetAttribute(dlg, "SIZE", "800x100") IupShow(dlg) IupMainLoop() IupClose()

SOLVED [17 hours later]: use IupSetAttribute(dlg, "SHRINK", "YES"). (The shrink attribute does not work on ftxt, btw, only the containing dialog.)

When there is not enough horizontal size for all the elements clipping starts from the right-hand-side; clipping always sacrifices the right most elements and tries to preserve the left most elements. I couldn't find a way to defeat this rule.
You could try MINSIZE as an attribute rather than SIZE. (But RHS clipping still seems to follow the same rules.)
You could create a dynamic layout that reads the size of the dialog and then sets the attributes or the elements.

Thanks for replying. As above SHRINK solved the immediate problem.
I did try MINSIZE on ftxt but it appears to have no effect on an IupText control.
I agree that MINSIZE on the IupDialog is probably the best/only way to prevent unwanted clipping.
What I have found, however, is that for some reason MINSIZE needs to be multiplied by {1.5,1.875}, ie width*1.5 and height*1.875.
For example (on an IupDialog) setting MINSIZE to "478x354" has the effect of 319x189, I needed "717x664" to achieve 478x354

Pete
