MiniGUI at least creates two system fonts: one mono-space logical font for single-byte charset, and one mono-space logical font for multi-byte charset. For the multi-byte charset, the width of one multi-byte character should be equal to the width of two single-byte characters. <hr><h2>Define Documentation</h2><a class="anchor" name="ga12" doxytag="gdi.h::SYSLOGFONT_CAPTION"></a><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">#define SYSLOGFONT_CAPTION 3 </td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td> </td> <td><p><dl compact><dt><b>See also:</b></dt><dd><a class="el" href="group__system__font.htm#ga1">GetSystemFont</a> </dd></dl><p>Definition at line <a class="el" href="gdi_8h-source.htm#l06124">6124</a> of file <a class="el" href="gdi_8h-source.htm">gdi.h</a>. </td> </tr></table><a class="anchor" name="ga14" doxytag="gdi.h::SYSLOGFONT_CONTROL"></a><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">#define SYSLOGFONT_CONTROL 5 </td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td> </td> <td><p><dl compact><dt><b>See also:</b></dt><dd><a class="el" href="group__system__font.htm#ga1">GetSystemFont</a> </dd></dl><p>Definition at line <a class="el" href="gdi_8h-source.htm#l06136">6136</a> of file <a class="el" href="gdi_8h-source.htm">gdi.h</a>. </td> </tr></table><a class="anchor" name="ga9" doxytag="gdi.h::SYSLOGFONT_DEFAULT"></a><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">#define SYSLOGFONT_DEFAULT 0 </td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td> </td> <td><p><dl compact><dt><b>See also:</b></dt><dd><a class="el" href="group__system__font.htm#ga1">GetSystemFont</a> </dd></dl><p>Definition at line <a class="el" href="gdi_8h-source.htm#l06106">6106</a> of file <a class="el" href="gdi_8h-source.htm">gdi.h</a>. </td> </tr></table><a class="anchor" name="ga11" doxytag="gdi.h::SYSLOGFONT_FIXED"></a><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">#define SYSLOGFONT_FIXED 2 </td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td> </td> <td><p><dl compact><dt><b>See also:</b></dt><dd><a class="el" href="group__system__font.htm#ga1">GetSystemFont</a> </dd></dl><p>Definition at line <a class="el" href="gdi_8h-source.htm#l06118">6118</a> of file <a class="el" href="gdi_8h-source.htm">gdi.h</a>. </td> </tr></table><a class="anchor" name="ga13" doxytag="gdi.h::SYSLOGFONT_MENU"></a><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">#define SYSLOGFONT_MENU 4 </td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td> </td> <td><p><dl compact><dt><b>See also:</b></dt><dd><a class="el" href="group__system__font.htm#ga1">GetSystemFont</a> </dd></dl><p>Definition at line <a class="el" href="gdi_8h-source.htm#l06130">6130</a> of file <a class="el" href="gdi_8h-source.htm">gdi.h</a>. </td> </tr></table><a class="anchor" name="ga10" doxytag="gdi.h::SYSLOGFONT_WCHAR_DEF"></a><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">#define SYSLOGFONT_WCHAR_DEF 1 </td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td> </td> <td><p><dl compact><dt><b>See also:</b></dt><dd><a class="el" href="group__system__font.htm#ga1">GetSystemFont</a> </dd></dl><p>Definition at line <a class="el" href="gdi_8h-source.htm#l06112">6112</a> of file <a class="el" href="gdi_8h-source.htm">gdi.h</a>. </td> </tr></table><hr><h2>Function Documentation</h2><a class="anchor" name="ga8" doxytag="gdi.h::GetSysCCharWidth"></a><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">int GUIAPI GetSysCCharWidth </td> <td class="md" valign="top">( </td> <td class="md" nowrap valign="top">void </td> <td class="mdname1" valign="top" nowrap> </td> <td class="md" valign="top"> ) </td> <td class="md" nowrap></td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td> </td> <td><p>Gets the width of a multi-byte character of the default system font. <p>This function returns the width of a multi-byte character of the default system font.
