Button(
onClick = {
raceOn = !raceOn
if (raceOn) {
text.value = "Stop!"
color.value = Color.Red
} else {
text.value = "Go!"
color.value = Color.Green
}
},
modifier = Modifier.background(color = color.value),
content = {
Text(
text = "${text.value}",
)
}
)
Using the code above, I got the attached image. What I want is the inside of the button to be green and not the background behind it. I couldn't the right property to modify.
Has anyone here tried to modify the Button background? Or perhaps suggest another solution. I tried the OutlinedButton and wasn't successful.
Thanks!
Use the MaterialTheme ButtonColors.
val colors: ButtonColors = ButtonDefaults.primaryButtonColors(backgroundColor = Color.Red)
Button(onClick = { /*TODO*/ }, colors = ButtonDefaults.primaryButtonColors()) {
// TODO
}
You can also update via setting the MaterialTheme defaults.
val wearColorPalette: Colors = Colors(
primary = Purple200,
primaryVariant = Purple700,
secondary = Teal200,
secondaryVariant = Teal200,
error = Red400,
onPrimary = Color.Black,
onSecondary = Color.Black,
onError = Color.Black
)
...
MaterialTheme(
colors = wearColorPalette,
typography = Typography,
// For shapes, we generally recommend using the default Material Wear shapes which are
// optimized for round and non-round devices.
content = content
)

I would like to create a View (stage, window) with partially transparent background. I have an image containing alpha channel
I used this kind of scenes in JavaFx, where I had to set the scene fill to null and the root node background color to transparent. I tried the same with TornadoFX:
class NextRoundView : View("Következő kör") {
override val root = vbox {
style {
backgroundColor = multi(Color.TRANSPARENT)
backgroundImage = multi(URI.create("/common/rope-bg-500x300.png"))
backgroundRepeat = multi(BackgroundRepeat.NO_REPEAT
to BackgroundRepeat.NO_REPEAT)
}
prefWidth = 500.0
prefHeight = 300.0
spacing = 20.0
padding = insets(50, 20)
text("A text") {
font = Font.font(40.0)
alignment = Pos.CENTER
}
button("OK")
{
font = Font.font(20.0)
action {
close()
}
}
sceneProperty().addListener{ _,_,n ->
n.fill = null
}
}
}
I'm calling the view like this:
NextRoundView().apply {
openModal(stageStyle = StageStyle.TRANSPARENT, block = true)
}
However, the stage is still has background:
What have I missed?
You've made a couple of mistakes that causes this. First of all, you must never manually instantiate UICompoenents (View, Fragment). Doing so will make them miss important life cycle callbacks. One important callback is onDock, which is the perfect place to manipulate the assigned scene. Changing these two issues and also cleaning up some syntax leads to this code, which successfully makes the background transparent:
class MyApp : App(MyView::class)
class MyView : View() {
override val root = stackpane {
button("open").action {
find<NextRoundView>().openModal(stageStyle = StageStyle.TRANSPARENT, block = true)
}
}
}
class NextRoundView : View("Következő kör") {
override val root = vbox {
style {
backgroundColor += Color.TRANSPARENT
backgroundImage += URI.create("/common/rope-bg-500x300.png")
backgroundRepeat += BackgroundRepeat.NO_REPEAT to BackgroundRepeat.NO_REPEAT
}
prefWidth = 500.0
prefHeight = 300.0
spacing = 20.0
padding = insets(50, 20)
text("A text") {
font = Font.font(40.0)
alignment = Pos.CENTER
}
button("OK") {
font = Font.font(20.0)
action {
close()
}
}
}
override fun onDock() {
currentStage?.scene?.fill = null
}
}
Here is a screenshot of the app with the changes implemented:
how to get windows system theme in UWP?
Light/Dark
var DefaultTheme = new Windows.UI.ViewManagement.UISettings();
WindowsThemeText.Text =DefaultTheme.UIElementColor(Windows.UI.ViewManagement.UIElementType.PageBackground).ToString();
i've tried that , but it doesnt shows theme....
uiTheme will return only two color #FF000000(Dark)or #FFFFFFFF (Light) according to system ui theme, so you can go this way.
you can fill dark or light color to your some ui element to show current system theme
var DefaultTheme = new Windows.UI.ViewManagement.UISettings();
var uiTheme = DefaultTheme.GetColorValue(Windows.UI.ViewManagement.UIColorType.Background).ToString();
if(uiTheme == "#FF000000")
{
WindowsThemeText.Text = "Dark";
}
else if(uiTheme == "#FFFFFFFF")
{
WindowsThemeText.Text = "Light";
}
/*
else
{
WindowsThemeText.Text = "Some new Updated theme found";
}
*/
So my project was to make two gallery pages. I called them "gallery1" and "gallery2".The gallery pages each have 5 thumbnails that act like buttons so when you click on em, it opens an swf of the picture. Now the problem is, it always opens on the top left, i want them to be in the middle of the page. This is the code for gallery1. Gallery 2 is the samething but with different pics. b1-b5 are the thumbnails.Please help.
var swfRequest1:URLRequest = new URLRequest("image1.swf");
var swfRequest2:URLRequest = new URLRequest("image2.swf");
var swfRequest3:URLRequest = new URLRequest("image3.swf");
var swfRequest4:URLRequest = new URLRequest("image4.swf");
var swfRequest5:URLRequest = new URLRequest("image5.swf");
var swfLoader:Loader = new Loader();
function opengal(evt:MouseEvent):void
{
var pTarget:String = evt.currentTarget.name;
if(pTarget == "b1")
{
swfLoader.load(swfRequest1);
addChild(swfLoader);
}
else if(pTarget == "b2")
{
swfLoader.load(swfRequest2);
addChild(swfLoader);
}
else if(pTarget == "b3")
{
swfLoader.load(swfRequest3);
addChild(swfLoader);
}
else if (pTarget == "b4")
{
swfLoader.load(swfRequest4);
addChild(swfLoader);
}
else if(pTarget == "b5")
{
swfLoader.load(swfRequest5);
addChild(swfLoader);
}
};
b1.addEventListener(MouseEvent.CLICK, opengal);
b2.addEventListener(MouseEvent.CLICK, opengal);
b3.addEventListener(MouseEvent.CLICK, opengal);
b4.addEventListener(MouseEvent.CLICK, opengal);
b5.addEventListener(MouseEvent.CLICK, opengal);
To set your loaded content in the middle of your stage, you can do like this :
// store files path into an array
var files:Array = ['image01.swf', 'image02.swf', 'image03.swf', 'image04.swf', 'image05.swf'];
var loader:Loader = new Loader();
// use loader.contentLoaderInfo to listen to Event.INIT
loader.contentLoaderInfo.addEventListener(
Event.INIT, function(e:Event):void {
// center our loader
loader.x = (stage.stageWidth - loader.width)/2;
loader.y = (stage.stageHeight - loader.height)/2;
})
addChild(loader);
function opengal(evt:MouseEvent):void {
// here the pTarget should be between 0 and 4 as an array index
var pTarget:int = Number((evt.currentTarget.name).substr(-1, 1)) - 1;
loader.load(new URLRequest(files[pTarget]));
};
...
I hope this can help you.
You have to position your swfLoader in the middle of the screen.
You can do this with this code:
swfLoader.x = (swfLoader.width - stage.stageWidth)/2; // and the y axis in a similar way
The required width and height properties can be retrieved when the contentLoaderInfo dispatches an Event.INIT.
I've been doing a essay about map on windows phone. I added pushpins default into map and its content is a image. I want to show information when I tap or click on pushpin, but I don't know what to do. I've just thought about use tooltip to show info, but I can't do it.
here is my createpushpin function.
can you help me? thank you for all kind of you!
private void CreateNewPushpin(object selectedItem)
{
var pushpinPrototype = selectedItem as Pushpinsmodel;
var pushpinicon = pushpinPrototype.Icon;
Pushpin pushpins = new Pushpin() { Tag = adress.Name };
pushpins.Background = new SolidColorBrush(Colors.Green);
pushpins.Location = new GeoCoordinate(lad, long);
ImageBrush image = new ImageBrush() {
ImageSource = new System.Windows.Media.Imaging.BitmapImage
(pushpinicon)};
Ellipse elip = new Ellipse()
{
Fill = image,
Name = adress.Name,
StrokeThickness = 10,
Height = 30,
Width = 30
};
pushpins.Content = elip;
var tooltipText = new ToolTip { Content = adress.Name};
ToolTipService.SetToolTip(pushpins, tooltipText);
map1.Children.Add(pushpins);
listpushpin.Add(pushpins);
this.map1.SetView(pushpins.Location, 18.0);
}
In my app I want to display a simple string within a popup when the user clicks on an image. For this I added a Tap gesture listener to the image and within the handler I have the following code:
private void GestureListener_Tap( object sender, GestureEventArgs e )
{
var img = sender as Image;
if( img == null ) {
return;
}
Point pos = e.GetPosition( img );
string text = "I'm a popup!";
var popup = new Popup() {
Child = new Border() {
BorderBrush = new SolidColorBrush( Colors.LightGray ),
Child = new TextBlock() {
Text = text,
TextWrapping = TextWrapping.Wrap,
},
},
HorizontalAlignment = HorizontalAlignment.Stretch,
HorizontalOffset = pos.X,
VerticalOffset = pos.Y,
Visibility = Visibility.Visible,
};
popup.IsOpen = true;
Debug.WriteLine( "GestureListener_Tap: " + text );
}
The call to WriteLine prints in the debugger output window but the popup doesn't get displayed. What am I doing wrong here?
Thanks for your help!
I tried your code and the Popup is displayed. I think the problem for you is the Position for the Image relative to the Mouse. Try to set another Background for the Parent Container and I think you'll see the Popup. You can also try to play around with
Point pos = e.GetPosition(null);
until you get the Position you require
