\ +WINGs is a small widget set with \ +a very nice look and feel. Its API is inspired \ +and its implementation borrows some ideas from interesting places.\ +

+The library is limited and its design is a little sloppy, \ +so it's not intended to build large or complex applications, just +small and complex ones. :-)\ +

Apart from the usual buttons and labels, it has some \ +interesting widgets like this list widget: "); + + { + WMList *list = WMCreateList(text); + char t[20]; + int i; + + WMResizeWidget(list, 60, 60); + for (i=0; i<7; i++) { + sprintf(t, "Item %i", i); + WMAddListItem(list, t); + } + + tb = WMCreateTextBlockWithObject(list, "{a list object or somesuch}", + WMBlackColor(scr), False, 0); + WMAppendTextBlock(text, tb); + + } + + + WMAppendTextStream(text, " a colour well such as this one: "); + { + WMColorWell *well; + well = WMCreateColorWell(text); + WMResizeWidget(well, 60, 40); + WMSetColorWellColor(well, + WMCreateRGBColor(scr, 0, 0, 0x8888, True)); + tb = WMCreateTextBlockWithObject(well, "{a button object}", + WMBlackColor(scr), False, 0); + WMAppendTextBlock(text, tb); + } + + WMAppendTextStream(text, + ", as well as a text widget: "); + + { + WMText *te = WMCreateText(text); + WMRealizeWidget(te); + WMResizeWidget(te, 120, 90); + WMSetTextParser(te, HTMLParser); + WMSetTextRelief(te, WRFlat); + // WMSetTextBackgroundColor(te, WMCreateNamedColor(scr, "Red", False)); + WMSetTextDefaultFont(te, WMSystemFontOfSize(scr, 10)); + WMAppendTextStream(te, "into which you can easily embed other " + "WINGs objects (such as this one), " + " without breaking a sweat (type in here)"); + tb = WMCreateTextBlockWithObject(te, "{a text object}", + WMBlackColor(scr), False, 0); + WMAppendTextBlock(text, tb); + WMSetTextHasVerticalScroller(te, False); + WMRefreshText(te, 0, 0); + } + + { + WMText *te = WMCreateText(text); + WMRealizeWidget(te); + WMResizeWidget(te, 120, 90); + WMSetTextParser(te, HTMLParser); + WMSetTextRelief(te, WRFlat); + // WMSetTextBackgroundColor(te, WMCreateNamedColor(scr, "Red", False)); + WMSetTextDefaultFont(te, WMSystemFontOfSize(scr, 10)); + WMAppendTextStream(te, "I always wanted to be able to have " + "a multi-column text editor in Unix for my reports, " + " now all I have to do is wait for someone to code it :-P"); + tb = WMCreateTextBlockWithObject(te, "{a text object}", + WMBlackColor(scr), False, 0); + WMAppendTextBlock(text, tb); + WMSetTextHasVerticalScroller(te, False); + WMRefreshText(te, 0, 0); } - //WMPrependTextStream(text, "this is prepended\n"); - //WMAppendTextStream(text, "blueplanet.rtf"); + + + + WMAppendTextStream(text, +" .
