I am using gwt for showing a dynamic image inside a td and the image is coming from a imagebundle but its showing the whole big image, which gwt makes during compilation, inside that td rather than showing specific part from that big image. I don't know what I am missing here... The problem is the image will be added and selected dynamically and I can't define a css everytime I add an image. If anyone of you can help me regarding it. Here is my code
My table cell is defined inside the UiBinder something like....
<ui:style>
.colourPickerCell {
background-repeat:no-repeat;
}
</ui:style>
<tr>
<td class="{style.colourPickerCell}" ui:field="colourPreviewSlot" rowspan="3" width="50%"></td>
</tr>
Function inside the presenter class:
public void newColorSelected(Image patternImage) {
Style patternImageStyle = patternImage.getElement().getStyle();
Style style = getColourPreviewSlot().getStyle();
style.setWidth(patternImage.getWidth(), Unit.PX);
style.setBackgroundImage(patternImageStyle.getBackgroundImage());
style.setLeft(-patternImage.getOriginLeft(), Unit.PX);
style.setTop(-patternImage.getOriginTop(), Unit.PX);
style.setHeight(patternImage.getHeight(), Unit.PX);
}
When I debug my code I get the html for patternImage object as:
<img id="..." style="backgrond:url(....) no-repeat -149px 12px;"/>
Best regards,
If you are using this image as a background sprite, it think you have to use background-position css property to "move" your image "behind" the td.
"left" and "top" properties are relative to the element you set the style on, not its underlying background image.

I have a list of arrays in a table displayed using repeat.for. I need to display tr row in blue color when "receiving.supplier === Scrap Separated" and blue color row when the result is "receiving.supplier === Scrap Sorted". Is there any way I can do it with if.bind but for String that I got in network tab. Here is my network and code.
I think this is purely a CSS question. You can have CSS rules based on [data-supplier] and assign a different background color based on the value of the supplier property.
The example CSS rules can be as follows.
tr[data-supplier="Scrap Separated"] {
background-color: blue;
}
tr[data-supplier="Scrap Sorted"] {
background-color: green;
}
And then bind the data-supplier property in the markup.
<tr data-supplier="${recieving.supplier}">
...
</tr>
Note that you cannot possibly nest div directly under tbody as that will be evicted by browser being non-conformed element as per the expected schema.
What I want to achive
I am using gatsby and want to design an image gallery. Clicking on one of the images shall open a modal, which: (1) is showing the image in maximum possible size, so that it still fits into the screen and (2) is centered in the screen.
My Code
/* imagemodal.js */
import React from 'react'
import * as ImagemodalStyles from './imagemodal.module.css'
import { Modal } from 'react-bootstrap'
import Img from 'gatsby-image'
import { useStaticQuery, graphql } from 'gatsby'
export default function Imagemodal() {
const data = useStaticQuery(graphql`
query {
file(relativePath: { eq: "images/mytestimage.jpg" }) {
childImageSharp {
fluid(maxWidth: 1200) {
...GatsbyImageSharpFluid
}
}
}
}
`)
return (
<div>
<Modal
show={true}
centered
className={ImagemodalStyles.imageModal}
dialogClassName={ImagemodalStyles.imageModalDialog}
onHide={(e) => console.log(e)}
>
<Modal.Header closeButton />
<Modal.Body className={ImagemodalStyles.imageModalBody}>
<h1>TestInhalt</h1>
<Img fluid={data.file.childImageSharp.fluid} />
</Modal.Body>
</Modal>
</div>
)
}
/* imagemodal.module.scss */
.imageModalDialog {
display: inline-block;
width: auto;
}
.imageModal {
text-align: center;
}
.imageModalBody img {
max-height: calc(100vh - 225px);
}
The Problem
The image does not scale to the screen size. The image is either too big - so it flows over the vieport - or it is too small. Secondly, the modal size does not respond to the image size correctly and / or is not centered.
What I tried
I used this suggestion for the CSS: How to limit the height of the modal?
I tried as well dozens of other CSS parameter combinations. But I could not find a working solution.
I tried to format the gatsby-image directly with a style-tag.
I tried as well react-modal but had similar problems.
Does anyone have a good solution to show a gatsby-image in full screen size in a responsive modal? For me it is okay to use either the bootstrap-modal or react-modal - or any other suitable solution.
Edit
In the end I ended up with a workaround. I used react-image-lightbox and took the Image-Source from gatsby-image as the input for lightbox. My component gets the data from the graphQL query in the props via props.imageData.
This works quite well for me:
import Lightbox from 'react-image-lightbox';
...
export default function Imagegallery(props) {
...
const allImages = props.imageData.edges
const [indexImageToShow, setIndexImageToShow] = useState()
...
return(
<Lightbox
mainSrc={allImages[indexImageToShow].node.childrenImageSharp[0].fluid.src}
...
/>
Special thanks to #FerranBuireu to point me to the right direction
Assuming that the functionality works as expected, as it seems, it's a matter of CSS rules, not React/Gatsby issue. The following rule:
.imageModalBody img {
max-height: calc(100vh - 225px);
}
It Will never be applied properly, since gatsby-image creates an output of HTML structure of nested <div>, <picture> and <img> so your rule will be affected by the inherited and relativity of the HTML structure. In other words, you are not pointing to the image itself with that rule because of the result HTML structure.
You should point to the <Img>, which indeed, it's a wrapper, not an <img>.
return (
<div>
<Modal show={true} onHide={handleClose} centered className={ImagemodalStyles.imageModal} dialogClassName={ImagemodalStyles.imageModalDialog}>
<Modal.Header closeButton />
<Modal.Body>
<Img className={ImagemodalStyles.imageModalBody} fluid={props.data.file.childImageSharp.fluid} />
</Modal.Body>
</Modal>
</div>
)
The snippet above will add the (spot the difference, without img):
.imageModalBody {
max-height: calc(100vh - 225px);
}
To the wrapper, which may or may not fix the issue, but at least will apply the rule correctly. It's difficult to know what's wrong without a CodeSandbox but you will apply the styles correctly with this workaround.
Keep always in mind that when using gatsby-image, the <img> it's profound in the resultant HTML structure so your styles should apply to the outer wrapper of it.
I want to show thumb-left icon on button in sapui5. thumb-left is not available. So can i choose thumb-down or thumb-up and rotate it on 90 Degree ?
How I can do it.
2ndly How to set the buttons color Red, Green ,Yellow. I set button type to Accept, Reject but it just make border of buton green ,red,
<Button id="btnNegative" type="Reject" icon="sap-icon://thumb-down" text="Negative" press=".onSentimentFeedBackButtonclick"></Button>
<Button id="btnNeutral" type="Accept" icon="sap-icon://thumb-up" text="Neutral" press=".onSentimentFeedBackButtonclick"></Button>
Here is a simple example
In your XML add a custom class to your button
<Button id="btnNeutral" class="myNeutralThumb" icon="sap-icon://thumb-up" text="Neutral" press=".onSentimentFeedBackButtonclick" />
Then in your style.css (or however your CSS file is named) add the following:
button.myNeutralThumb .sapMBtnInner {
border-color: #ff0 !important;
}
button.myNeutralThumb .sapMBtnIcon {
transform: rotate(90deg);
color: #ff0 !important;
}
The first style changes the color of the button's border. Probably that should be the same color as the icon.
The second style rotates your thumb icon and changes its color.
If you also want to change the background-color of your button, put something like background-color: #fff; in the second style rule.
Edit: Replaced complicated and long and non-future-proof CSS style rule with short CSS rule + !important
I'm using GWT 2.4. I have a view with some simple content ...
final Image ajaxImage = new Image("loading.gif");
final Grid grid = new Grid(1, 2);
grid.setText(0, 0, "Loading...");
grid.setWidget(0, 1, ajaxImage);
this.container = new FlowPanel();
this.container.add(grid);
rootPanel = new SimplePanel();
rootPanel.add(this.container);
I would like this content to be centered horizontally and vertically in the containing panel, which is a FlowPanel, if that matters. How do I do that?
Thanks, - Dave
I know how to do it in a verticalpanel.
VerticalPanel panelPrincipal3 = new VerticalPanel();//Esto es el panel central, donde se centra todo
panelPrincipal3.setWidth("100%");
panelPrincipal3.setHeight("100%");
panelPrincipal3.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_CENTER);
panelPrincipal3.setVerticalAlignment(HasVerticalAlignment.ALIGN_MIDDLE);
panelPrincipal3.add(/*your panel*/);//here yo add whatever yo want, and should be centered
if you were to put your FlowPanel as a direct child of your RootPanel, you can try to set its height to 100%. so if you only have a grid as a child component for your container, you can set its alignments like this:
container.setCellHorizontalAlignment( grid, HasHorizontalAlignment.ALIGN_CENTER );
container.setCellVerticalAlignment( grid, HasVerticalAlignment.ALIGN_MIDDLE );
But if you ever change your mind and you'll switch to UiBinder, you can do something like this:
<g:VerticalPanel spacing="0" width="100%" height="100%" ui:field="mainPanel">
<g:Cell horizontalAlignment="ALIGN_CENTER" verticalAlignment="ALIGN_MIDDLE">
<!-- content goes here -->
</g:Cell>
</g:VerticalPanel>
with css? margin:0 auto; and position:absolute; top:50%; ?
I'm creating a MenuBar, and I want to have it display a little icon when there are sub-elements to be displayed. I thought I could achieve this like so:
interface ActionHeroResources extends ClientBundle, MenuBar.Resources
{
#Source("actionhero.css")
public ActionHeroCSS css();
#Override
#Source("agw-dropdown.png")
ImageResource menuBarSubMenuIcon();
}
private static final ActionHeroResources RESOURCES = GWT.create(ActionHeroResources.class);
MenuBar actionMenu = new MenuBar(true, RESOURCES);
public ActionHero()
{
actionMenu.addItem("Select", aSelectMenuFullOfOptions);
}
But the menu appears with the word "Select" an no icon! I'm positive my ImageResource is working correctly because I use menuBarSubMenuIcon().getURL() from the same resource later, and my image shows up just as you'd expect. In the HTML generated by GWT, there is absolutely no distinction between the items with MenuBars as children and the items with Commands. My CSS is working fine.
Any thoughts?
Try overriding the CSS style for .gwt-MenuBar-vertical .subMenuIcon-selected, like this:
.gwt-MenuBar-vertical .subMenuIcon-selected {
background: none;
}
I use this for my own selected items and it works great:
.gwt-MenuBar-vertical .subMenuIcon-selected {
background: url(images/hand_pointer.png) no-repeat 0px 0px;
}
The problem was ultimately that the popup panels that form the submenus take their stylename from the parent, but append a dependent stylename. I don't know of a way to predict what that dependent stylename will be, since the original stylename is obfuscated. I worked around this problem by using the more generic .gwt-MenuBar popup stylename. This only works because I only have one style of popup menu in my program - I'm not sure what I would do if I wanted two popups to look different!
Hopefully, in later gwt releases, the MenuBar styles will come more closely from the resources passed to the menubar and make less use of dependent style names.
You can simply set a css rule for the that appears in the sub menu like this:
.subMenuIcon > img {
/* override gwt sub menu icon */
width: 6px !important;
height: 11px !important;
background: url('your-image-relative-path.png') no-repeat 0px 0px !important;
}
