Programming MDI with MiniGUI - Part II [Updated 22nd march 2009]

After tinkering with MDI programming and with the help of Grigory of HMG Extended Forum :-






Basic syntax for a Browse which works perfectly in a non-MDI environment is as follows :-

[ @ , ] BROWSE
[ ID ]
[ OF | PARENT | DIALOG ]
WIDTH
HEIGHT
HEADERS
WIDTHS
WORKAREA
FIELDS
[ VALUE ]
[ FONT SIZE ]
[ BOLD ] [ ITALIC ] [ UNDERLINE ] [ STRIKEOUT ]
[ TOOLTIP ]
[ BACKCOLOR ]
[ DYNAMICBACKCOLOR ]
[ DYNAMICFORECOLOR ]
[ FONTCOLOR ]
[ ON GOTFOCUS | ]
[ ON CHANGE | ]
[ ON LOSTFOCUS | ]
[ [ ON DBLCLICK | ] | [ EDIT | ALLOWEDIT [ INPLACE ] ] [ APPEND | ALLOWAPPEND] ]
[ ON HEADCLICK | ]
[ WHEN ]
[ VALID ]
[ VALIDMESSAGES ]
[ READONLY ]
[ LOCK ]
[ DELETE ]
[ NOLINES ]
[ IMAGE ]
[ JUSTIFY ]
[ NOVSCROLL ]
[ HELPID ]
[ BREAK ]

However, please note that for MDI environment:-

[ [ ON DBLCLICK | ] | [ EDIT | ALLOWEDIT [ INPLACE ] ] [ APPEND | ALLOWAPPEND] ]

a) EDIT/APPEND does not work
b) You may use EDIT INPLACE

This is exactly why I wrote my own UDF to replace them :-)

Finally, perfected (with the help of Grigory of HarbourMiniGUI Forum) TILING/CASCADE of Child Windows populated with different DBF

MDI Programming with MiniGui [Updated 12th March 2009]

Having pushed the very stable HMG to it's limits and as documented in my previous articles, I was encouraged by Sudip and decided to take a serious look at HMG Extended ie MiniGui as most of the apps that I have in mind must be MDI in nature..

This is what I started With


What did I do Next ?

I took the codes from FAS4HMG and copied the Project folder under the MiniGui folder. I was then able to recompile it as a MIDI apps with some minor adjustments.
