|---|---|---|---|
| 1 | + | **LCLIntf** is a Lazarus unit that provides compatibility with Delphi in a cross-platform way. It also contains some additional functions | |
| 2 | + | ||
| 3 | + | On defining a new [[Lazarus Packages|package]], make sure that [[LCL]] is added as requirement to get rid of 'missing LCLIntf' error. | |
| 4 | + | ||
| 5 | + | ## functions and procedures | |
| 6 | + | ||
| 7 | + | It can replace code in the (Delphi) Windows unit. | |
