components

问题 Let's say we have a component called TopComponent with a template like this: <ng-template #top> <inner-selector #inner></inner-selector> </ng-template> It's code is simple: //... imports ... @Component({ // selector, styles etc }) export class TopComponent implements AfterViewInit { @ViewChild('top') topComp : NgbModal; // NgbModal is a type provided by some 3rd-party library // I can't modify it ngAfterViewInit() { // let's access the #inner component from here } } I can access the #top

问题 I am developing a Delphi 10.1 VCL application for Windows. For integer or float input I need a number input field which is connected with a slider.

问题 I'm looking for a (preferably free) component for Delphi for users to easily select about 100 different colours. I've currently got one as part of DevExpress's editors, but it only has about 20 proper colours to choose, with a bunch of other 'Windows' colours like clHighlight, clBtnFace, etc. It's for regular users, so would like to avoid requiring them to manually select RGB values. Something similar to the colour picker in MS Paint might work, or something that lists X11/web colours: http:/

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago .
