This extension +replaces the older Xt/Motif Support Extension included with earlier +versions of TQt. +<p> The TQt Motif Extension consists of the following classes: +<p> <ul> +<li> <a href="qmotif.html">TQMotif</a> - Provides the basis of the TQt Motif Extension. +<li> <a href="qmotifwidget.html">TQMotifWidget</a> - Provides the <a href="qwidget.html">TQWidget</a> API for Motif widgets. +<li> <a href="qmotifdialog.html">TQMotifDialog</a> - Provides the <a href="qdialog.html">TQDialog</a> API for Motif dialogs. +<li> <a href="qxtwidget.html">TQXtWidget</a> - The Xt/Motif integration widget from the previous +Xt/Motif extension. This class is unsupported and has many known +problems and limitations. It is provided only to keep existing source +working; it should not be used in new code. +</ul> +<p> <h3> Additional Documentation +</h3> +<a name="1-1"></a><p> <ul> +<p> <li> <a href="motif-examples.html">Examples</a> +<li> <a href="motif-walkthrough.html">Migration Walkthrough</a> - A +complete migration of a Motif based program to the TQt toolkit. +<p> </ul> +<p> <h2> Common Problems +</h2> +<a name="2"></a><p> <h3> Incorrect CDE Color Scheme +</h3> +<a name="2-1"></a><p> <a href="qmotifwidget.html">TQMotifWidget</a> and <a href="qmotifdialog.html">TQMotifDialog</a> will use the same Visual, Colormap +and color depth that <a href="qapplication.html">TQApplication</a> uses. When using CDE, the color +scheme may be incorrect when using a Visual, Colormap and color depth +that is not the default. To work around this problem, add the +following resource string to your startup files (for example, +<tt>$HOME/.dt/sessions/current/dt.resources</tt>): +<p> <pre> + *userColorObj: false +</pre> + +<p> <h3> X11 Header Conflicts +</h3> +<a name="2-2"></a><p> The X11 headers define some constants that conflict with the TQt +headers. The solution is to include all TQt headers first, followed by +headers from this extension, and all Xt/Motif and X11 headers last. +For example: +<p> <pre> + // TQt headers first + #include <<a href="qapplication-h.html">qapplication.h</a>> + #include <<a href="qpushbutton-h.html">qpushbutton.h</a>> + #include <<a href="qsocket-h.html">qsocket.h</a>> + ... + + // TQMotif* headers next + #include <<a href="qmotif-h.html">qmotif.h</a>> + #include <<a href="qmotifdialog-h.html">qmotifdialog.h</a>> + #include <<a href="qmotifwidget-h.html">qmotifwidget.h</a>> + + // Xt/Motif and X11 headers last + #include <X11/Xlib.h> + #include <Xt/Intrinsic.h> + #include <Xm/Xm.h> + ... +</pre> + +<p> <h3> Multiple Screen Support +</h3> +<a name="2-3"></a><p> <a href="qmotifwidget.html">TQMotifWidget</a> can be used together with <a href="qdesktopwidget.html">TQDesktopWidget</a> to create +top-level windows on multiple screens. A common mistake is to create +a TQMotifWidget on a non-default screen while the Xt/Motif widgets are +created on the default screen. The solution is to specify the screen +to both TQMotifWidget and the Xt/Motif child. For example: +<p> <pre> + Display *dpy = TQMotif::<a href="qmotif.html#x11Display">x11Display</a>(); + Arg args[1]; + + // make sure both TQMotifWidget and the XmMainWindow are on screen 1 + XtSetArg(args[0], XtNscreen, ScreenOfDisplay(dpy, 1)); + <a href="qmotifwidget.html">TQMotifWidget</a> *toplevel = + new <a href="qmotifwidget.html">TQMotifWidget</a>(TQApplication::<a href="qapplication.html#desktop">desktop</a>()->screen(1), + xmMainWindowWidgetClass, args, 1, "mainwindow"); +</pre> + +<p> +<!-- eof --> +<p><address><hr><div align=center> +<table width=100% cellspacing=0 border=0><tr> +<td>Copyright © 2007 +<a href="troll.html">Trolltech</a><td align=center><a href="trademarks.html">Trademarks</a> +<td align=right><div align=right>TQt 3.3.8</div> +</table></div></address></body> +</html> |
