Ib yam li ntawd, AWT pob hauv Java yog dab tsi? Cov java ua . aw package yog lub ntsiab pob ntawm AWT , los yog Abstract Windowing Toolkit. Nws muaj cov chav kawm rau cov duab kos, suav nrog Java 2D graphics muaj peev xwm nkag tau rau hauv Java 2 platform, thiab tseem txhais cov qauv siv graphical user interface (GUI) rau Java.
Ib yam li ntawd, tib neeg nug, dab tsi yog AWT tswj?
AWT Controls tsis muaj dab tsi tab sis AWT Cheebtsam uas tso cai rau tus neeg siv sib txuas lus nrog tus neeg siv ntau txoj hauv kev. Nws kuj tseem tuaj yeem hais tias kev sib cuam tshuam nrog tus neeg siv yuav ua raws li peb lub ntsiab lus hauv qab no: UI Elements. layouts.
Dab tsi yog qhov sib txawv AWT Cheebtsam?
