method to building a screen with many objects

[Tom]

Maxz, look at the "TABMERGE.PRG" in "..\Samples\TabPage" of your eXpress++-installation!

[rdonnay]

Have you tried this?

Code: Select all

DCGETOPTIONS ;
  BUSYMESSAGE 'Building Screen Objects. Please wait..'   COLOR GRA_CLR_DARKGREEN  

[Maxz]

yes Roger,
i've tried BUSYMESSAGE option but I don't really like it because the progress bar (I think it's a thread) is positioned centrally on the screen and is untied from the window where the screen is composed

I would prefer to check the construction of the screen trying to optimize the speed and maintaining the similarity with other windows applications

I would like to explore Tom's suggestion ...

Roger replaced the DC_MergeGetLists()-concept (which is still alive) with the MERGECHILDREN clause some years ago. Look at the sample!

This is how I use(d) DC_MergGetLists:

Code: Select all

@ 0,0 DCTABPAGE oTab ... GOTFOCUS {||IF(!lShowTab,lShowTab := ShowTab(oTab,GetList,oDialog),NIL)}

... somewhere else:

FUNCTION ShowTab(oOwner,aGetList,oDialog)
LOCAL Getlist := {}

... build parts

DCREAD GUI SAVE PARENT oOwner
DC_MergeGetLists(oGetList,GetList)
RETURN .T.

Hello,
take a look at the XDEMO program from Roger, samples 5, MergeGetlist2.
It shows the building of tabpages and the elements on demand.

It shows the building of tabpages and the elements on demand.

My shortened code showed almost the same.

Sorry Tom, i did not realize your sample.
