When I click on a row within a TableView the row will be highlighted blue. How is it possible to disable this feature?
I've already tried to set the background to white, but the problem is that the row-color isn't white in every row.
Does anybody know what to do?
best regards
EDIT:
In the image below you see the blue color of the second row. This highlighting should be removed.
If you really want to do this (I agree with #kleopatra in the comments that it would make life difficult for the user) you can revert the colors for selected rows with an external css file:
.table-row-cell:filled:selected {
-fx-background: -fx-control-inner-background ;
-fx-background-color: -fx-table-cell-border-color, -fx-background ;
-fx-background-insets: 0, 0 0 1 0 ;
-fx-table-cell-border-color: derive(-fx-color, 5%);
}
.table-row-cell:odd:filled:selected {
-fx-background: -fx-control-inner-background-alt ;
}

I've got a Xamarin Forms cross-platform application (iOS and Android), and on one of the screens I want a list with details:
Heading 1
Detail 1
Detail 2
Detail 3
Heading 2
Detail 1
Heading 3
Detail 1
Detail 2
As you can see, the amount of detail under each heading is variable.
I want the page to display at first with just the headings:
Heading 1
Heading 2
Heading 3
And then when the user presses on a heading, the details for that particular heading appear. Pretty standard stuff.
I've tried several different ways to get this to work, the only path that seems open to me is to have a StackLayout where I define a bunch of labels:
new StackLayout
{
Orientation = StackOrientation.Vertical,
Children =
{
new Label { Text = "Heading 1" },
new Label { Text = " Detail 1\n Detail 2\n Detail 3", IsVisible = false },
new Label { Text = "Heading 2" },
new Label { Text = " Detail 1", IsVisible = false },
new Label { Text = "Heading 3" },
new Label { Text = " Detail 1\n Detail 2", IsVisible = false }
}
}
I then add a TapGestureRecognizer to the heading labels, and when tapped I toggle the value of IsVisible for the detail labels. It works!
The only thing I don't like, is that there is no transition. I click on the heading label and BAM the detail label appears (correctly pushing down all the following labels to make space for itself). I would like an animation so that when I click on the header, the space beneath the header "slowly" opens up to reveal the detail.
As I read about animations online, one possibility is to set the HeightRequest of the detail labels to zero (instead of hiding them with IsVisible=false) and then creating an animation that "slowly" changes the HeightRequest from zero to the actual height of the label. And that's where I run into a problem.
I can't figure out how to get Xamarin to tell me the height of my "details" label.
If I inspect the Height and HeightRequest properties of my details label right after creating it, they are both -1 (no big surprise there). If I inspect those same two properties when I click on the heading, they are still -1. The only way I've found to get the height of my detail label, is to set the detail label visible, call ForceLayout() on my stack layout, store the detail label height, and then set the detail label invisible again. The problem with that is that I sometimes see the detail label flash visible for an instant while I do this.
What's the best/recommended way to accomplish my desired UI?
You can use the Animation API.
Read the blog about it - Creating Animations with Xamarin.Forms.
In particular for your scenario you can use the FadeTo method to animate the Opacity property of a Visual Element.
Eg :
await image.FadeTo (1, 4000);
For more information, see Animation.
In your case my suggested approach would be for showing a label, to set opacity of label to 0, then make it visible, and then use FadeTo to make the opacity to 1.
Use the opposite to hide the label, set opacity 0 via FadeTo, then set IsVisible to false.
If I understand right your problem the only thing you need is to avoid the flash on the label, if this is the case then you can set the Opacity to 0, in this way the label will not be visible until you set again the opacity to 1.
I can suggest you to make a custom XF control (to use as item DataTemplate) as follow:
2 vertical parts:
The header part (A) (when you click on it it will show the second part)
The second part is a 'Listview' control (B) that is empty at the beginning
When you click on (A):
it will show (B)
It will start to populate (B) with your details elements
The trick in my mind is to implement a method that populate the listview (B) item by item (getting them from your viewmodel) with some delay (a few milliseconds) between each insertion and maybe a 'fadeTo' effect too in the same time.
You can see here what I mean (see the "Fade" section):
Insert / fade list item effect sample in HTML
You can improve your template as you want, by embedding the two parts into a 'border' for instance, to make a graphical separation...
Tell me if it's unclear, all you need is time :)
And maybe if you are ready, you can try to make native controls / animations...
Here is the plunker created http://plnkr.co/edit/5DhDmI1Odhrys4jYDwIB?p=preview
I have associated textbox with ng-grid filter.
$scope.filterOptions = {
filterText:''
}
$scope.$watch('filterText',function(){
$scope.filterOptions.filterText=$scope.filterText;
});
If you enter "moroni" in the text box, only one row in grid will be displayed. But at the right, white space is visible. Is there a way to fix it.
First row in the plunker example is having very big string, When text is very long, only part of it is displayed. Is it possible to break the string and display it in multiple lines.
You can fix the text not wrapping issue by setting the rowHeight in gridoptions to value that fits your longest string:
rowHeight:50
And add this definition to your css:
.ngCellText {
white-space: unset;
}
The width whitespace issue is clearly a bug in ng-grid. This grid is not really a table but a lot of positioned and measured divs that look like a table. Seems the developers forgot to add some extra width to the row when no scrollbar is visible. You can only overcome this if you patch the code (not recommended) or setting the gridheight to a value in which all rows can be displayed without scrollbars.
.gridStyle {
border: 1px solid rgb(212,212,212);
width: 500px;
height: 300px
}
Look at this Plunker.
Anyhow, since these are mere unpractical hacks, I suggest you have a look at table based directive like trNgGrid which has all the features of ng-grid but is way more flexible when it comes to dynamic row heights.
I started a new project in slickgrid.
I am working this sample.
How can I change the background color of the row I want ?
For example : first row backcolor to red , second row backcolor to blue ...
Thanks for your help.
If you always want your first row red, your second row blue etc then define it in css using the nth-of-type selector and the .slick-row class selector:
/*Colour the first row red*/
.slick-row:nth-of-type(1){
background: #FF0000;
}
/*Colour the second row blue*/
.slick-row:nth-of-type(2){
background: #0000FF;
}
I'm using kendo tooltips on a graphic (within an anchor link) which is 24px tall. Accordingly, when the tooltip shows up (default position of bottom), it covers the bottom third of the graphic and so the bottom third of the graphic can't be clicked.
I can do the following:
.k-tooltip {
margin-top: 8px;
}
But the problem with this is that if the tooltip is on a graphic at the bottom of the page, the position will be "top" instead of "bottom" but it'll now be covering about 1/2 the graphic instead of just a third because it's still being pushed down by 8px.
What I'd like is if the position is bottom, then the margin-top is 8px, but if the position is top, the the margin-bottom is 8px.
Thanks for any help you can provide!

Would this one help you?
http://dojo.telerik.com/amoZE/5
var tooltip = $("#demo").kendoTooltip({
filter: "a",
show: function (e) {
var position = e.sender.options.position;
if (position == "bottom") {
e.sender.popup.element.css("margin-top", "10px");
} else if(position == "top") {
e.sender.popup.element.css("margin-bottom", "10px");
}
}
}).data("kendoTooltip");
Thank you for your answer, jarno-lahtinen. It was very helpful!
Two problems came up with it and I would like to document the solutions here:
1. Property Error in Typescript
I am using TS and it gave me the following error:
"Property popup does not exist on type Tooltip" for e.sender.popup. I am not sure if this is due to a newer version of Kendo, or of missing type definitions.
Solution:
you can use this.popup instead.
2. Not working for position: "top"
Unfortunately, the "margin-bottom" has absolutely no effect because the popup is positioned "absolute" using top/left.
Solution:
this.popup.element.css("margin-top", "-10px");
This will shift the popup upwards by 10 pixels
I’m using Qt Creator. In my GUI I use a tab widget. This widget should have the same grey background color as the main window (picture A). I accomplished this by editing the Style Sheet in Qt Designer with:
background-colour: rgb(240, 240, 240);
But now I have two new problems I can’t solve:
The buttons (--> Send) are not rounded anymore.
The edit boxes’ background color has changed to grey, too.
Befor I changed the Style Sheet the GUI looked like in Picture B.
I also tried
QPalette pal = m_pUi->tabWidget->palette();
pal.setColor(m_pUi->tabWidget->backgroundRole(), Qt::blue);
m_pUi->tabWidget->setPalette(pal);
but this only changes the color behind the tabs, not the entire color of the whole "tab-window-surface".
Do I have to make additional style descriptions or is there an more simple solution?
Picture A - with Style Sheet
Picture B - without Style Sheet
I had the same problem and I discovered that you need to set this attribute to each one of your tabs:
ui->tab->setAutoFillBackground(true);
I'm not sure, but I think that also is necessary set that attribute to the QTabWidget as such.
I hope this help.
The "things" you want to access are called QTabBars. Keeping that in mind you can write a stylesheet like this:
QTabBar::tab
{
background: #48555E;
color: white;
border-color: #48555E;
}
QTabBar::tab:selected,
QTabBar::tab:hover
{
border-top-color: #1D2A32;
border-color: #40494E;
color: black;
background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #C1D8E8, stop: 1 #F0F5F8);
}
