I have a Vaadin 22 application that features a view that has 2 Select fields next to each other. They belong together (are actually dropdowns for month and year) and they require only a single label, which is longer than the component on the left.
I've tried to put it on the left component but then it gets cut off:
What is the easiest way to accomplish this?
It seems you might want to try the Custom Field component for this.
Another alternative is to customize the CSS a bit:
vaadin-select::part(label) {
overflow: visible;
}

I would like to use FormLayout where one of the fields is visible depending on another field. Is there a way to keep the formatting the same, that is for all the fields after it to stay in their same position when another component is invisible.
Below is the code to reproduce as well as a screenshots of what I would like compared to the current behavior. In essence each time you select the combobox you make the "Year Joined Team" field invisible/visible.
TextField nameTextField = new TextField("Name");
ComboBox<String> teamComboBox = new ComboBox<>("Team");
DatePicker yearJoinedDatePicker = new DatePicker("Year Joined Team");
TextField moreFieldsTextFields = new TextField("More fields");
FormLayout formLayout = new FormLayout();
formLayout.setWidth("600px");
formLayout.setResponsiveSteps(new FormLayout.ResponsiveStep("0", 2, FormLayout.ResponsiveStep.LabelsPosition.TOP));
formLayout.add(nameTextField,
teamComboBox, yearJoinedDatePicker,
moreFieldsTextFields);
teamComboBox.setItems(List.of("One", "Two"));
teamComboBox.addValueChangeListener(change -> yearJoinedDatePicker.setVisible(!yearJoinedDatePicker.isVisible()));
formLayout.setColspan(nameTextField, 2);
add(formLayout);
Ideally the goal is to have the fields below the yearJoinedTeamDatePicker component to stay below so that all other components below continue to be aligned correctly when it's set to be invisible.
Instead what actually happens is that all the components are shifted on field to the left, as if the invisible component is no longer part of the FormLayout. Meaning the moreFieldsTextField is now on a different row, and if everything is setup for two columns every row will be incorrect. I understand that this makes sense in some context but in a FormLayout is there a way to keep the form formatted if a component is invisible?
If for example I had firstname and lastname as two side by side fields they would now be on different rows as shown below:
A very hacky solution would be to add in a Span component or something like that and make it invisible when the yearJoinedDatePicker field is visible, and invisible when it's visible. Basically fill it in with an empty field when it's invisible. That is a hacky workaround but it doesn't seem like an appropriate solution. With that in mind is there a way to keep the formatting/layout if a component is invisible?
What you are trying to achieve is sort of defying the purpose of FormLayout. FormLayout has css flex rules to wrap elements / components by row. Thus if you switch visibility of a component, the behavior is as you described.
One thing you could do, is to wrap "Team" and "Year joined team" inside e.g. HorizontalLayout and set
formLayout.setColspan(horizontalLayout, 2);
See, also my previous answer about FormLayout https://stackoverflow.com/a/69270190/8962195
If you want to keep the place, maybe it's vable for you to set the field ti disabled with setEnabled.
I'm not sure how it would behave, but you could try CSS display: none instead of the setVisibility(false).
I am starting to make my Vaadin web app responsive. Reading Vaadin docs, I managed to make a CssLayout flexible such that an image is shown either to the left of a text section or in a separate row depending on available width.
Now I want to make my login form flexible. By default, captions are moved to the left of the fields. How can I achieve that the captions are moved to the top of the fields when a certain width is reached? Is that even possible with FormLayout?
Can't really imagine that it is possible with CSS because the FormLayout is rendered as HTML table. If so, what is a simple alternative?
That is not possible with FormLayout. Structure of FormLayout is not flexible. Also there is not simple alternative for that. You can use CssLayout or create your own component container.
Starting point for this can be extending AbstractComponentContainer as described in Creating a simple component container
I would like to add an icon to the header of my data grid as it is done in Thunderbird.
There is an icon that is above the vertical scrollbar, no matter the position of the horizontal scrollbar. This icon allows the setup of the columns.
In Delphi there a lot of different grid components, that allow customizations and adding icons to there cells / header cells. But I could not find any component that has an area above the vertical scrollbar that is fixed, which when clicked allows some action. I could even use the VirtualTreeView component to emulate the grid, if it turns out to be easier to customize that component.
I am looking for some guidance on what need to be done to get that functionality.
Thanks,
Thomas
VirtualTreeView in Listbox mode would be nice, because of it's speed, great documentation and ease use in MVC-like patterns. Delphi tempts to store data in the visual components themselves, which letter causes troubles. While VTW allwos the same, it also allows to acutally separate data from GUI, and i like it.
But i am surprised by your claim "which when clicked allows some action.".
Even most basic components allow it:
http://docwiki.embarcadero.com/Libraries/XE2/en/Vcl.Grids.TCustomGrid.OnFixedCellClick
So could you make more detaiils, why you cannot use standard components ? with screenshot and editors, how u want it rendered, where you want to click and what kind of action should happen ?
does any one know if there is an example available for sliding panels in jquery? If so, can someone send me a link? This is what I want to accomplish.
On my main screen I want to have three divisions. One right column that covers half the screen and then the left column divided in two rows. I want to expand and/or shrink the right column and/or left column and/or the top row in the left column and/or the bottom row in the left column.
Think og it as an IDE with the left side of the coding area and right side as project explorer and the properties. The coder would like to see any three of the sections at once or would like to expand each working area.
I am looking for a jquery solution for such!
Thanks
Sounds like the way jsfiddle.net works
This is available as a plugin. http://docs.jquery.com/UI/Resizable
You could also use the jQuery splitter plugin: http://www.methvin.com/splitter/
Also see (2011): http://jcubic.wordpress.com/2011/03/06/jquery-splitter-split-container/
Flexigrid is a new (2012) option: http://flexigrid.info/
The most robust solution for this is to use the jQuery layout plugin. You can find it here: http://layout.jquery-dev.net/
I have two radiobuttons in a TRadioGroup. All the logic behind how they are supposed to work is fine. But the TRadioGroup controler has a frame around it that I thought I would be able to delete using a border property or something like that. But the control doesn't seem to have any property that bears any resemblance to a border/frame. How do I set the controler to not include a frame?
TRadioGroup does not support what you are looking for. Place two TRadioButton components onto a TPanel instead. Then you can make it look how you want.
I don't think you can hide the border on a standard radio group box. It looks like you could create a custom descendant and override the painting if drawing normally, but that approach could be a bit more involved with theme support. Overall it sounds like a lot of work to go that route.
The next most obvious approach is to replace the radio group with a number of individual radio buttons on a container such as a panel. That would work and would be simple code but it could get messy. It seems a lot of busy work for little gain and I am lazy enough to look for another option.
There is a kludge you can use. If you put the radio group on a panel rather than directly onto the form (or other background) you can make the panel under-sized compared to the radio group. You want the panel to be as big as the interior of the radio group but not as big as the border. Then set the top and left of the radio group to negative numbers so that the border falls outside the parent panel. The border is not visible this way.
I know it's not best practice but I had a similar issue and couldn't redesign everything. So I did this to simply hide the border (and works great so far).
HANDLE Region = CreateRectRgn(3, 3, RadioGroup->Width-3, RadioGroup->Height-3) ;
SetWindowRgn(RadioGroup->Handle, Region, true);
