When I use html2canvas on a page with a fixed header, it renders the header near the bottom of the canvas rather than where it should be at the top. Is there a workaround for this so that it renders fixed elements in the correct position?
Without seeing your code, it is possible that you need to specify the vertical-align property of the header's children elements to be text-top.
Setting scrollX and scrollY to 0 sorted the issue.
html2canvas(document.body,{scrollX: 0, scrollY: 0})

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.

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
I've got a long text field which wraps to another page, the problem is that the border on first page does not matches end of page...
I guess I coul've fixed it by adding some Frame element, but I couldn't achive it by now.
thanks!
I guess the cause of this problem was "Strech type: relative to tallest object"
my solution was to put all the fields in an outlined frame
and disable fields bottom border
I have a text field followed by a static text field and I am trying to do 2 things with it:
Get the text field to stretch horizontally (not wrap) when text is longer then the field width and
Push the static text field right when the text field to the left of it stretches
Both of the fields are contained within a frame.
I have both fields set to positionType=float and the text field set to stretchWithOverflow=true, which enable text to wrap vertically but not stretch horizontally.
Is it possible to achieve 1 and 2 above? If so How?
Instead of having 2 text fields (dynamic and static), you can have 1 text field with value as $F{Field} + "statix text". This will probably fix your issue. Also, you can set the "width" and "stretch with overflow" properties, as per your requirements.
Well it's bad news!! According to Jaspersoft's documentation on stretching fields it is not possible to stretch the width of a field:
"Usually, the stretching process refers to the height adjustment only.
When stretching report elements, adjusting the width could affect also
the page width and raise unexpected errors at runtime (for instance,
truncated information could be printed out on pages). This is why
stretching an element let its width unchanged, while its height gets
definitely enlarged in order to make room for all information that
have to be displayed." (Jaspersoft documentation [v4.5.0], 2011)
However a solution to the original issue can be found here thanks to #mdahlman
Just select text field and from its textfield properties choose "stretch with overflow" and it will change its height dynamically according to text .enter image description here
Is there a way to change the space between a spark form item and its content(textinput, conbobox)? I already set to 0 the "gap" property of the form, but still there is a lot of vertical space left between the form inputs.
Set the gap to -14 to get no gap between the items
<s:Form>
<s:layout>
<s:FormLayout gap="-14"/>
</s:layout>
<s:FormItem .....>
</s:Form>
The spark skin for formItem has left/right variables set based on "columns." I.e. left="column1:10" means the element is 10 pixels to the right of column 1.
So, create the skin, reduce those numbers in the "content" column area and check it.
Reducing all those numbers and the gap should tighten, along with setting the gap in form layout.
If you want to change the vertical gap between each Spark Form Item, create a custom skin based on FormSkin and change the gap property FormLayout.
If you want to change the horizontal gap between skin parts (labelDisplay, indicatorDisplay, helpContentGroup, ...), you need to create a custom skin based on FormItemSkin and change the ConstraintColumn values
I changed in my custom FormItem skin as followed, and it worked for me:
before:
<s:ConstraintRow id="row1" baseline="maxAscent:10" height="100%"/>
after:
<s:ConstraintRow id="row1" baseline="maxAscent:0" height="100%"/>
There are no paddingLeft, paddingRight etc. properties in FormItemLayout yet.
I have the three following lines and the first two line gets all the images on the document and hides all, but then when I add the third line shows all the images.
What I need its to hide only the images with the attribute alt=minimize and alt=maximize but for some reason hides all the images.
$('img').attr('alt', 'minimize').css("display","none");
$('img').attr('alt', 'maximize').css("display","none");
$('img').attr('alt', 'logo').css("display","inline");
I am using IE7, but it should be compatible with IE6 and IE8.
Any help would be very much appreciated.
Thanks.
I'm thinking you are not using the attr function correctly, might you be looking for the attribute equals selector?:
$('img[alt=minimize]').css("display","none");
What you did with your code was,
Select all images
Change their alt attribute to 'minimize'
Hide them
Select all images
Change their alt attribute to 'maximize'
Hide them
Select all images
Change their alt attribute to 'logo'
Hide them
what you do: you take every img in document and set alt to logo and then set display: inline;.
Note, that attr('alt',string) doesn't filter all images to those with alt=string, but rather sets alt attribute to string on all images.
What you want to use is this:
$('img[alt="minimize"]').css...
$('img[alt="maximize"]').css...
$('img[alt="logo"]').css...
In the call $('img').attr('alt', 'logo').css("display","inline"); the "attr" doesen't filter the set of dom elements You catch with $("img").
If you want to hide everithing but not the image with the attribute 'alt' = 'logo' I think You can:
give it an Id of logo and then calling: $("img").not("#logo").hide()
from the jquery website:
hide():
The matched elements will be hidden
immediately, with no animation. This
is roughly equivalent to calling
.css('display', 'none'), except that
the value of the display property is
saved in jQuery's data cache so that
display can later be restored to its
initial value. If an element has a
display value of inline, then is
hidden and shown, it will once again
be displayed inline.
and
attr( attributeName )
Returns: String
Description: Get the value of an
attribute for the first element in the
set of matched elements.
If instead you want to hide all the maximize and minimize images (both share the "imize" part of the attribute):
$(parentElement).find("img[#attr $= '*imize']").hide()
OP is referring to
http://dev.w3.org/csswg/css3-values/#attr
alt I think is simply a string type, not "logo" whatever that is, that is not a data type.
try that. in fact, you can look up alt in the html5 img
http://www.w3.org/TR/html5/the-img-element.html#the-img-element
http://www.w3.org/TR/html5/the-img-element.html#attr-img-alt
http://www.w3.org/TR/html5/the-img-element.html#alt
(in order of reference clicking, last one is the target)
even if this isn't the exact answer (it should be), it should be a step in the right direction.
I am actually trying myself to figure out how to reference a css property within css with attr() - it's mentioned within the top URL. if I had my druthers, I could be using css calc() along with it, but that's draft. maybe I can get it to work...
