/*IupMultiline Advanced Example in C Shows a dialog with a multiline, a text, a list and some buttons. You can test the multiline attributes by clicking on the buttons. Each button is related to an attribute. Select if you want to set or get an attribute using the dropdown list. The value in the text will be used as value when a button is pressed. */ /* IupMultiLine example */ /* ANSI C libraries include */ #include #include /* IUP libraries include */ #include /****************************************************************************** * Function: * * Set Attribute * * * * Description: * * Sets an attribute with the value in the text * * * * Parameters received: * * attribute - attribute to be set * * * * Value returned: * * IUP_DEFAULT * ******************************************************************************/ int set_attribute (char* attribute) { char string_message [50]; Ihandle *mltline; Ihandle *text; mltline = IupGetHandle ("mltline"); text = IupGetHandle ("text"); IupSetAttribute (mltline, attribute, IupGetAttribute (text, "VALUE")); sprintf (string_message, "Attribute %s set with value %s", attribute, IupGetAttribute (text, "VALUE")); IupMessage ("Set attribute", string_message); return IUP_DEFAULT; } /****************************************************************************** * Function: * * Get attribute * * * * Description: * * Get an attribute of the multiline and shows it in the text * * * * Parameters received: * * attribute - attribute to be get * * * * Value returned: * * IUP_DEFAULT * ******************************************************************************/ int get_attribute (char* attribute) { char string_message [50]; Ihandle *mltline; Ihandle *text; mltline = IupGetHandle ("mltline"); text = IupGetHandle ("text"); IupSetAttribute (text, "VALUE", IupGetAttribute(mltline, attribute)); sprintf (string_message, "Attribute %s get with value %s", attribute, IupGetAttribute (text, "VALUE")); IupMessage ("Get attribute", string_message); return IUP_DEFAULT; } /****************************************************************************** * Functions: * * Append button callback * * * * Description: * * Appends text to the multiline.
