问题描述

试图从包含按钮的网格渲染器中打开一个对话框.问题是对话框不遵守指定的大小.

Trying to open a dialog from a grid renderer which contain a button. The problem is that the dialog isn't respecting the specified size.

我尝试设置对话框的宽度和高度，但它不会影响 DOM 元素，只会影响它的子元素(看起来不像预期的那样)

I've tried setting the width and height of the dialog but it doesn't affect the DOM element only its childs (which doesn't look as expected)

    @Override
    public VerticalLayout createComponent(P item) {
                // this simply create a VerticalLayout
        VerticalLayout layout = super.createComponent(item);

        HorizontalLayout subLayout = new HorizontalLayout();
        subLayout.setWidthFull();
        subLayout.setDefaultVerticalComponentAlignment(Alignment.CENTER);

        this.button = new MSButton(this.colorClass, this.vaadinIcon);
        this.button.addClickListener(event -> {
            this.parent = item;
            this.grid.getDataProvider().refreshAll();
            this.dialog.open();
        });

        subLayout.add(this.button);
        layout.add(subLayout);

        return layout;
    }

    private void constructDialog() {
        this.dialog = new Dialog();

        H1 titleHolder = new H1(this.getDialogTitle());
        titleHolder.addClassName("mt-0");
        titleHolder.setWidthFull();

        H3 headerHolder = new H3(this.getDialogHeaderText());
        headerHolder.addClassName("mt-0");
        headerHolder.setWidthFull();

        HorizontalLayout headerRow = new HorizontalLayout();
        headerRow.add(headerHolder);
        headerRow.add(this.getDialogHeaderIcon().create());
        headerRow.setWidthFull();

        MSButton closeButton = new MSButton("Fermer", "success",
                VaadinIcon.CHECK_CIRCLE_O, event -> {
                    dialog.close();
                });

        HorizontalLayout footerRow = new HorizontalLayout();
        footerRow.add(closeButton);

        VerticalLayout footer = new VerticalLayout();
        footer.setDefaultHorizontalComponentAlignment(Alignment.END);
        footer.setAlignItems(Alignment.END);
        footer.setWidthFull();
        footer.add(footerRow);

        VerticalLayout container = new VerticalLayout();
        container.add(titleHolder);
        container.add(headerHolder);
        container.add(this.grid);
        container.add(footer);

        this.dialog.setWidth("700px");
        this.dialog.setHeight("500px");

        this.dialog.add(container);
    }
