This call fills the xwa structure and one variable in that structure is "xwa.map_state". This is TRUE if the window is on the display and FALSE if it is minimized or not on the current display. A test of this variable after a caller event was all I needed to know if I should set my variables and raise the window. </pre> </blockquote> <pre wrap=""> The value of "form->visible" or the return value of the function fl_form_s_visible() only get changed by calls of the fl_hide_form() or fl_free_form() function but not by the window getting unmapped when it's iconified (XForms doesn't deal with the Unmap/Map event except by calling XRefreshKeyboardMapping() on a MappingNotify event). So even when the window is in iconified state it's treated as "visible". As you already found out you have to query the window attributes to find out if the window is mapped (but note that the "map_state" value isn't just a boolean, there are three possible values it can have, IsUnmapped (0), IsUnviewable (1) and IsViewable (2), the IsUnviewable value undicating that while the window itself is mapped a parent window is unmapped so it's not really shown on the screen). So the combination of "form->visible" being set to FL_VISIBLE (or the corresponding return value of fl_form_is_visible()) together with XGetWindowAttributes() telling you that the window is not mapped looks like the best indication of the window being in iconified state. </pre> </blockquote> I was wondering what the second state was. Thanks. <blockquote cite="mid:20081019221727.GA27479@toerring.de" type="cite"> <pre wrap=""> Perhaps I should add a function with a name like fl_form_is_iconified() to make it easier to check for this. While the name of the function fl_form_is_visible() is a bit unlucky I wouldn't like to change its behaviour since that might break programs that rely on it to tell you if a form has been hidden by a call of fl_hide_form() etc. or not.</pre> </blockquote> You are right. The "fl_form_is_iconified()"is preferable. <blockquote cite="mid:20081019221727.GA27479@toerring.de" type="cite"> <pre wrap=""> Or do you need a callback for a form's window becoming iconified or de- iconified? </pre> </blockquote> This type of callback would be very useful if it can be done. Not only for my app but for any instance where a form is minimized or maximized. Knowing a forms size has changed or is no longer visible would allow for font changes if maximized, no visual work need be done if minimized and do the work if returned to normal state. I am sure there are more uses. <blockquote cite="mid:20081019221727.GA27479@toerring.de" type="cite"> <pre wrap=""> Best regards, Jens </pre> </blockquote> Thanks, Serge <div class="moz-signature">-- <meta content="text/html; " http-equiv="content-type"> <title>Signature</title> <meta content="Serge Bromow" name="author"> <pre class="moz-signature" cols="72">Serge Bromow DineAmix Inc. <a class="moz-txt-link-rfc2396E" href="mailto:serge@dineamix.ca"><serge@dineamix.ca></a> 888 411-6636 Ottawa, Canada. <a class="moz-txt-link-freetext" href="http://www.dineamix.ca">http://www.dineamix.ca</a> IMPORTANT NOTICE: This message is intended only for the use of the individual or entity to which it is addressed.
