gadgets.window.adjustHeight() calculates height of the gadget incorrectly - opensocial

I am writing an opensocial gadget. My structure is something like this:
<div style="height:200px;overflow:auto;">
<div id="dComment">Comments are loaded here.</div>
</div>
I update the content of the "dComment" every second, and its content gets some scrolling.
In my gadget I have specified <Require feature="dynamic-height"/>
When I use gadgets.windows.adjustHeight() it calculates the height of the content regardless that I have made some part of it hidden through adjusting a height for my outer div. As a result I see a huge white space below my content !!!
I know that I can specify height for adjustHeight function. But then it means that on every update I have to calculate the height of the gadget myself, and I don't want to do it (if possible).
Can someone explain to me why it happens and how can I solve it ?

Instead of visibility:hidden use display:none

Is there way to set detailRowHeight prop to 100% in ag-grid?

Recently started working on a master detail structure angular ag-grid. The structure has two levels of master-detail nesting. I need to fix the heights of inner - 2 grids such that they occupy all available real estate on the screen. Currently, ag-grid defaults it to 300 px and a lot of whitespace or unused space appears on a 1920x1200 screen resolution monitor. I also need to have fixed headers for all grids.
Any ideas or pointers would be appreciated...
Update: Referring to a forked version of plunker example from ag-grid here - https://next.plnkr.co/edit/yUzo4EqONEmgCmIw This is simple and basic set up for master-detail grid.
Note that: I haven't set any detail row height and have setup just one record to show up in the grid to test for the issue.
If you run the plunker code and view the result in separate window, notice that the inner / child grid doesn't occupy all the space available below it. In other words, it doesn't take as much as space/height available from parent container (master's detail row). The default 300px master detailRowHeight is making height fixed for inner grid. Also, from documentation, detailRowHeight prop doesn't seem to take something similar as 100% or 100vh and only takes fixed pixels number. Added a picture of the example below and the height / unused space I referred
We have different resolutions that users use to view data in grid and the heights of inner grids need to auto-adjust taking max. available space to show most information in the grids.
You could try something like this, I pulled it from the documentation:
In your component.ts file add this method. If it's a detail row it will apply different calculations than the other rows.
public rowHeight(params) {
if (params.node && params.node.detail) {
var offset = 80;
var allDetailRowHeight = params.data.callRecords.length * 28;
return allDetailRowHeight + offset;
} else {
// otherwise return fixed master row height
return 25;
}
};
In your template add the following: [getRowHeight]="rowHeight"
<ag-grid-angular
#agGrid
style="width: 100%; height: 100%;"
id="myGrid"
class="ag-theme-balham"
[columnDefs]="columnDefs"
[masterDetail]="true"
[detailCellRendererParams]="detailCellRendererParams"
[getRowHeight]="rowHeight"
[rowData]="rowData"
(gridReady)="onGridReady($event)"
></ag-grid-angular>
Hopefully this will get you moving forward. Good Luck!

So I don't have a great, full solution for you but as a starting point I would use CSS to override the styles ag-grid is setting - I don't think detailRowHeight is going to help.
Here's my plunk getting close to what you want with some simple CSS I put in index.html. You can use !important to override ag-grid styles, or you could use javascript to set the CSS after ag-grid does. I prefer !important in this case and don't have to worry about timing.
https://next.plnkr.co/edit/mmXBBJE5Wa1JrX7v
The problem I wasn't going to get into is getting it to dynamically fill up available space, depending on the row selected, scroll position, etc. I can't think of any simple way to achieve that - I do this type of thing in grid often and end up writing javascript to calculate the available space, and then set the CSS in javascript.
In ag-grid you have the possibility to set auto height for details.
Set grid property detailRowAutoHeight=true to have the detail grid to dynamically change it's height to fit it's rows.
const gridOptions = {
// dynamically set row height for all detail grids
detailRowAutoHeight: true,
// other grid options ...
}
However if you are providing your own detail component...
detailCellRenderer: 'MyOwnDetailsComponent',
then, it might not work and you will still need to provide an grid options height detail content through...
detailRowHeight: 560,
Please see the ag-grid documentation here

AngularDart: Child does not fit to width parent

I would like to fit child <material-expansionpanel> that is into a AngularDart component invoked into <material-tab> to reach parent´s width.
I used [flex] directive, but did not work. How could I to do this work?
See the picture. The <material-expansionpanel> does not expand to right side.
Code:
<!-- parent -->
<material-tab-panel>
<material-tab [flex] label="Formação do Preço">
<precomi-formacaopreco></precomi-formacaopreco>
</material-tab>
<!-- child <precomi-formacaopreco> -->
<div>
<material-expansionpanel name="Atividade Principal" flex [showSaveCancel]="false">
<material-radio-group flex>
<material-radio [checked]="true">Comércio</material-radio>
<material-radio>Indústria</material-radio>
<material-radio>Serviços</material-radio>
</material-radio-group>
</material-expansionpanel>
...
</div
I do not think [flex] does anything in particular here. If you don't constraint width then expansion panel should take whole horizontal space. If that doesn't happen you can try filing an issue to angular_components with runnable reproduction instructions.
I think the issue might be that your <div> the <material-expansionpanel> does not expand to the width of page. Can you try setting the width of the <div> to 100%?

LayoutPanel with right alignment

I'm using a layout panel with some layers. One of the layers is quite simple but I want it to have a float: right on the element. But this is actually not working because subwidgets are styled with style="postition: absolute; left: 0px; ..." which overrides the styling and so the subpanels/widgets will always be placed on the left. Any workaround for this?
After adding your element to your layout container, did you try setWidgetHorizontalPosition ?
If above method does not work and you want to use float right, maybe you can use a non-layout system with FlowPanel maybe. Otherwise you will have to fix the position and width/height of your components but you may loose responsive design.
Last trick : If you really need to change the absolute style. In your component do something like this (do this after your component has been added to the dom)
this.getElement().getParent().getStyle().set.....
You can reset whatever property you want but this might break your layout

gwt 2.4 DataGrid - auto set column width?

I have a problem with DataGrid in gwt 2.4. I made table with CellTable, and everything worked fine. But I needed fixed header, and then just replaced CellTable with DataGrid. I had problem with .css file, but than has been resolved.
Now, the problem is that every column have fixed width, and table put every row just in visible part of screen.
This is new and old screen shots, to make things more clear :)

Can someone help to make old looking, but with fixed header.
You can set a fixed width for each column of the data grid:
dataGrid.setColumnWidth(sampleColumn, 40, Unit.PX);
and expand the total data grid width:
dataGrid.setWidth("100%"); // choose the most useful in your app
dataGrid.setWidth("1400px");
I'm not sure what the right answer is, but I don't think the previous responders understood the question.
Basically, you want dataGrid to use "table-layout: auto" instead of "fixed". This is what cellTable does. Table columns are auto-sized based on content.
This is easy for the content table, but to get the header-freeze, dataGrid is using a separate div/table for the header. Therefore, the header table's columns need to be explicitly sized based on the data table. They also need to be resized anytime the table changes (browser resizes, etc.). I plan on adding resizeable cols on a dataGrid, so I'll be hitting this same challenge soon I expect and will update when I have something more explicit if anyone is still tracking this thread...
need to wrap your content in your td with an inner div. and make sure the overflow-x is set to hidden.
table {
overflow: hidden;
white-space: nowrap;
table-layout: fixed;
}
td div{
overflow-x:hidden;
}

Css background layers and 100% height div's

Imagine the following code.
<body id="first_bg_layer">
<div id="second_bg_layer">
<div id="third_bg_layer">
</div>
</div>
</div>
Each layer has a different background that is static/repeated to achieve the desired effect. I need all layers to fill up the screen, otherwise the background will be broken. The background is split in layers to minimize the image sizes.
Setting min-height to 100% doesn't work for various reasons. Is there any way to do this?
Edit: If I set #second_bg_layer to height:100% and #third_bg_layer to min-height:100%, that works. But then the #second_bg_layer is locked to 100%, and will not be expanded more.
What I want to do is to set the min-height on both div's, or some other solution.
Is a trick I read sometime ago, and applied as seen bellow, if I recall well... As said just above by others for the first part, I'd set :
html,html body {height:100%;}
Then, a div containing all content. A sort of wrapper if you want to call it so.
...wrapper div to which I'd set {height:100%;min-height: 100%;}
In its class or id.
But sadly IE does not support min-height, nor height:auto, so...
just set first the IE case line: {height: 100%;}
and then the css that will apply to other browsers:
html>body whatever_the_div_class {height: auto;min-height: 100%;}
Finally, do a footer div to put it outside this wrapper div, just after it, to which css properties you will add:
height 1%; clear:both
(the 1% is like often happens, IE needs some "space" or will do weird things)
Well, let's hope it helps :)
Did you set the HTML and BODY height to 100% with 0 margins? If not, do that, if so, make sure your div elements are positioned correctly.
If you just aren't getting a full width and height out of the body area, then maybe what you are asking for is this:
html, body {
height: 100%; width: 100%;
}
/* And perhaps adding this if you're not using any reset CSS */
html, body {
margin: 0; padding: 0;
}
If its not, I'm not sure what you are having trouble with, but a background-image cannot be displayed outside of its selected element. If you want to differ the background layer from the layer itself then I would suggest using an additional div that has width/height: 100%; position: absolute; top/left: 0; and background: url(...); to hold the background image.
