Packages Question

[Kattanapilot]

Sorry for the Noob question but I am getting back in to SUF 9.5.1. My packages screen will allow to go "next" without checking a "box". How do I prevent this from happening? My default state is "unchecked"

thanks!

First, on the Select Packages attributes, uncheck the Enabled option for the Next button, so it shows like this by default:



Now, in the On Ctrl Message event script, make it so that the button becomes enabled when at least one package is selected for installation. If no package is selected, make sure that the button becomes disabled again, as somebody could select and de-select a package, so the button must become enabled, then disabled again.

Currently I have: (On Crtl Message)

- These actions are triggered by the controls on the screen.

if(e_CtrlID == CTRL_SELECT_PACKAGE_TREE) then
-- the control message is from the select packages tree...

-- if the current selection changed (i.e. a different package was selected),
-- update the description field
if(e_MsgID == MSGID_ONSELCHANGED) then

-- get the selected item's description
local strText = e_Details.Description;

-- if the selected item is a package, add its size to the description
if(e_Details.Type == 1) then
strText = strText.."\n( "..String.GetFormattedSize(e_Details.Size).." )";
end

-- update the description field
DlgStaticText.SetProperties(CTRL_STATICTEXT_BODY, {Text=strText});
end


-- if an item's state changed (i.e. a package was turned on or off),
-- update the 'Total space required:' message
if(e_MsgID == MSGID_ONSTATECHANGED) then

-- calculate the amount of space required for the installation
_SpaceRequired = SetupData.CalculateRequiredSpace();

-- set %SpaceRequired% to a string with an appropriate unit of measurement (e.g. "0 bytes")
SessionVar.Set("%SpaceRequired%", String.GetFormattedSize(_SpaceRequired) );

-- from _SUF70_Global_Functions.lua:
-- update the 'Total space required:' message (expands any session variables in it)
g_UpdateStaticTextCtrl(CTRL_STATICTEXT_SPACEREQUIR ED, "IDS_CTRL_STATICTEXT_SPACEREQUIRED");
end
end

I was looking in the Action list to anything that resembled "enabled" button, but I could not find anything that resembled that.

thanks,
Cal

You need to use

DlgButton.SetProperties(CTRL_BUTTON_NEXT, {Enabled=true});

if you want to enable the button via Lua script.
