Inno Setup entry (25) -- Inno Setup class reference (11)

Let's talk about the tnewchecklistbox class today.
This class is similar to ListBox, but the following items can be selected using checkbox or radiobutton, which is a complex type.

This class inherits from Tcustomlistbox has the following attributes and functions:
Tnewchecklistbox = Class (tcustomlistbox) function addcheckbox (const acaption, asubitem: string; alevel: byte; achecked, aenabled, ahasinternalchildren, struct: Boolean; aobject: tobject): integer; function addgroup (acaption, asubitem: string; alevel: byte; aobject: tobject): integer; function addradiobutton (const acaption, asubitem: string; alevel: byte; achecked, aenabled: Boolean; aobject: tobject): integer; function checkitem (const index: integer; const aoperation: tcheckitemoperation): Boolean; property checked [index: integer]: Boolean; read write; property State [index: integer]: tcheckboxstate; read write; property itemcaption [index: integer]: string; read write; property itemenabled [index: integer]: Boolean; read write; property itemlevel [index: integer]: byte; read; property itemobject [index: integer]: tobject; read write; property itemsubitem [index: integer]: string; read write; property allowgrayed: Boolean; read write; property flat: Boolean; read write; property minitemheight: integer; read write; property offset: integer; read write; property onclickcheck: tpolicyevent; read write; property borderstyle: tborderstyle; read write; property color: tcolor; read write; property Font: tfont; read write; property sorted: Boolean; read write; property onclick: tpolicyevent; read write; property ondblclick: tpolicyevent; read write; property onkeydown: tkeyevent; read write; property onkeypress: tkeypressevent; read write; property onkeyup: tkeyevent; read write; property showlines: Boolean; read write; property wanttabs: Boolean; read write; property requireradioselection: Boolean; read write; End

Test example:

[Code] varmypage: twizardpage; clb1, clb2: tnewchecklistbox; LBL: tlabel; I, index: integer;

Procedure clbclickcheck (Sender: tobject); begin LBL. caption: = ''; for I: = 1 to 3 do if clb1.checked [I] Then LBL. caption: = clb1.itemcaption [I] + ''; for I: = 5 to 7 do if clb1.checked [I] Then LBL. caption: = LBL. caption + clb1.itemcaption [I] + ''; end; Procedure initializewizard (); begin mypage: = createcustompage (wpwelcome, 'title: Custom page', 'description: this is my custom page '); LBL: = tlabel. create (mypage); LBL. parent: = mypage. surface; clb1: = tnewchecklistbox. create (mypage); clb1.width: = mypage. surfacewidth; clb1.top: = 20; clb1.height: = scale( 200); clb1.flat: = true; clb1.parent: = mypage. surface; clb1.addcheckbox ('operating system ',', 0, true, true, false, true, nil); clb1.addradiobutton ('windows 2000 ',', 1, false, true, nil); clb1.addradiobutton ('windows XP ', '', 1, true, true, nil); clb1.addradiobutton ('windows 7','', 1, false, true, nil); clb1.addcheckbox ('installable components', '', 0, true, true, false, true, nil); clb1.addcheckbox ('component 1','', 1, true, true, false, true, nil); clb1.addcheckbox ('component 2', '', 1, true, true, false, true, nil ); clb1.addcheckbox ('component 3', '', 1, false, true, false, true, nil); clb1.onclickcheck :=@ clbclickcheck; end; the running effect is as follows:

 

TheProcedure clbclickcheck dynamically adjusts automatically according to the selected options.
