I have a png background and I need to locate 5 texts on top of this png (see pic.). I am thinking of wrapping it all in a bundle of HStacks within one VStack. Something like this:
Vstack {
HStack {
Txt1
Txt2
}
HStack {
Txt3
}
HStack {
Txt4
Txt5
}
}
The question is how do I adjust it all so it is precisely in the spots like on the example picture. And more importantly, how do I keep this setup consistent throughout several devices? I tried to run on several devices and texts are all over the place, jumping up and down, left and right. There's got to be some kind of a simple geometry-like solution or the way to pin down the Vstack dimensions to my png size. Any advice?

Goal is to show a text the largest possible on the screen in any orientation so the solution I had in mind was to make the font size considerably big but add a minimum scale factor modifier to it such as the following.
struct ContentView: View {
var body: some View {
Text("U")
.font(.system(size: 2000
)) .multilineTextAlignment(.center).minimumScaleFactor(0.001).padding()
}
}
how ever what is shown on canvas is the picture below and is trimmed on the right side.
This will achieve the look you are after:
Text("U")
.font(.system(size: 2000))
.minimumScaleFactor(.leastNonzeroMagnitude)
I am using Extendscript for Photoshop CS5 to change the text of a text layer. Is there a way of checking whether the text fits e.g. by checking whether it overflows after changing the content?
I created a solution that works perfectly fine :). Maybe someone else can use it as well. Let me know if it works for you too!
function scaleTextToFitBox(textLayer) {
var fitInsideBoxDimensions = getLayerDimensions(textLayer);
while(fitInsideBoxDimensions.height < getRealTextLayerDimensions(textLayer).height) {
var fontSize = parseInt(textLayer.textItem.size);
textLayer.textItem.size = new UnitValue(fontSize * 0.95, "px");
}
}
function getRealTextLayerDimensions(textLayer) {
var textLayerCopy = textLayer.duplicate(activeDocument, ElementPlacement.INSIDE);
textLayerCopy.textItem.height = activeDocument.height;
textLayerCopy.rasterize(RasterizeType.TEXTCONTENTS);
var dimensions = getLayerDimensions(textLayerCopy);
textLayerCopy.remove();
return dimensions;
}
function getLayerDimensions(layer) {
return {
width: layer.bounds[2] - layer.bounds[0],
height: layer.bounds[3] - layer.bounds[1]
};
}
How to use / Explanation
Create a text layer that has a defined width and height.
You can change the text layers contents and then call scaleTextToFitBox(textLayer);
The function will change the text/font size until the text fits inside the box (so that no text is invisible)!
The script decreases the font size by 5% (* 0.95) each step until the texts fits inside the box. You can change the multiplier to achieve a more precise result or to increase performance.
I haven't found a way to do this directly. But I've used the following technique to determine the height I needed for a textbox (I wanted to keep the width constant) before.
expand the textbox's height well beyond what is needed to accommodate the text inside it.
duplicate the layer
rasterize the duplicate
measure the bounds of the rasterized layer.
adjust the bounds of the original text layer as needed
delete the rasterized duplicate
Totally roundabout - but it did work.
I am trying to make a (new in 10.10) NSSplitViewItem collapse and uncollapse whilst moving its containing window so as to keep the whole thing "in place".
The problem is that I am getting a twitch in the animation (as seen here).
The code where I'm doing the collapsing is this:
func togglePanel(panelID: Int) {
if let splitViewItem = self.splitViewItems[panelID] as? NSSplitViewItem {
// Toggle the collapsed state
NSAnimationContext.runAnimationGroup({ context in
// special case for the left panel
if panelID == 0 {
var windowFrame = self.view.window.frame
let panelWidth = splitViewItem.viewController.view.frame.width
if splitViewItem.collapsed {
windowFrame.origin.x -= panelWidth
windowFrame.size.width += panelWidth
} else {
windowFrame.origin.x += panelWidth
windowFrame.size.width -= panelWidth
}
self.view.window.animator().setFrame(windowFrame, display: true)
}
splitViewItem.animator().collapsed = !splitViewItem.collapsed
}, completionHandler: nil)
}
}
I am aware of the "Don't cross the streams" issue (from session 213, WWDC'13) where a window resizing animation running on the main thread and a core animation collapse animation running on a separate thread interfere with each other. Putting the splitViewItem collapse animation onto the main thread seems like the wrong approach and I've got a nagging feeling there's a much better way of doing this that I'm missing.
Since I am not finding any documentation on the NSSplitViewItems anywhere (yet) I would appreciate any insights on this.
I have the little test project on GitHub here if anyone wants a look.
Update The project mentioned has now been updated with the solution.
Thanks,
Teo
The problem is similar to the "don't cross the streams" issue in that there are two drivers to the animation you've created: (1) the split view item (2) the window, and they're not in sync.
In the example from the '13 Cocoa Animations talk, constraints were setup to result in the correct within-window animation as only the window's frame was animated.
Something similar could be tried here -- only animating the window's frame and not the split view item, but since the item manages the constraints used to (un)collapse, the app can't control exactly how within-window content animates:
Instead the split view item animation could completely drive the animation and use NSWindow's -anchorAttributeForOrientation: to describe how the window's frame is affected.
if let splitViewItem = self.splitViewItems[panelID] as? NSSplitViewItem {
let window = self.view.window
if panelID == 0 {
// The Trailing edge of the window is "anchored", alternatively it could be the Right edge
window.setAnchorAttribute(.Trailing, forOrientation:.Horizontal)
}
splitViewItem.animator().collapsed = !splitViewItem.collapsed
}
For anyone using Objective C and targeting 10.11 El Capitan.
This did the trick for me, didn't need to set AnchorAttributes.
splitViewItem.collapsed = YES;
I have a JavaFX app which contains a line chart. I want users to be able to select the color of each series in the chart. Since the selection is dynamic I can't use static CSS to set the colors. I also have other controls that I need to set to the same color as the associated series. It's possible to set the line color of a series dynamically using code like this:
series.getNode().setStyle("-fx-stroke: " + color + ";");
That works well and I can use the user-specified color on the associated controls.
My problem is that I also need to set the color of the symbols for each series to the same color. I can't find any way to do that dynamically. All of the tutorials, documentation, and posts that I've read on the topic point to the static CSS approach.
Most charting widgets make this sort of thing very easy to do, but I've found no clues here or on the Oracle forums. Any guidance would be greatly appreciated.
-- Update --
I've found no way to do this other than to enumerate every data point in every series, grab the associated symbol node and set the style individually. Not what I was hoping for. In the process I realized that the default Node allocated for a symbol is a StackPane. I didn't need that flexibility so I replaced it with a Rectangle. This made rendering faster.
I'm late to the game, but maybe someone can use my solution. What worked for me, was iterating through every item in the data series and setting the CSS style for each one.
for (int index = 0; index < series.getData().size(); index++) {
XYChart.Data dataPoint = series.getData().get(index);
Node lineSymbol = dataPoint.getNode().lookup(".chart-line-symbol");
lineSymbol.setStyle("-fx-background-color: #00ff00, #000000; -fx-background-insets: 0, 2;\n" +
" -fx-background-radius: 3px;\n" +
" -fx-padding: 3px;");
}
I was stuck with a similar problem. I don't know upfront which data is going to be added to the graph, so I can't make use of a fixed stylesheet.
I came up with this solution. This code listens for new series added to graph. For every added series, it will create a new listener for data added to the series.
This listener will look up which series this is, the 0th, 1st, etc and then find the two nodes for the coloring of the line and of the legend/symbol.
As soon as it has set both, it can unsubscribe.
Problem can be that the legend/symbol node is not available yet when you receive the callback on the first added datapoint.
I'm aware it's very convoluted and I'm open to hear improvements.
At least it will give you the option to dynamically set the color to anything you want.
final LineChart<Number, Number> chart = new LineChart<>(new NumberAxis(), new NumberAxis());
final ObservableList<Series<Number, Number>> series = chart.getData();
series.addListener(new ListChangeListener<Series<Number, Number>>() {
#Override
public void onChanged(Change<? extends Series<Number, Number>> change) {
ObservableList<? extends Series<Number, Number>> list = change.getList();
for (final Series<Number, Number> serie : list) {
serie.getData().addListener(new ListChangeListener<Data<Number, Number>>() {
#Override
public void onChanged(Change<? extends Data<Number, Number>> ignore) {
int index = series.indexOf(serie);
Set<Node> nodes = chart.lookupAll(".series" + index);
boolean isStyleSet = false;
for (Node n : nodes) {
if (StringUtils.isEmpty(n.getStyle())) {
String css = "-fx-stroke: %s; -fx-background-color: %s, white; ";
String color = //assign dynamically here, for instance based on the name of the series
n.setStyle(String.format(css, color, color));
isStyleSet = true;
}
}
if (!isStyleSet & nodes.size() > 1) {
serie.getData().removeListener(this);
}
}
});
}
}
});
I had a problem which might be slightly different (possibly more complex); I needed to style some nodes of a series one color, others within the same series another color (I also needed to be able to change the allocation of color dynamically). I am working in JavaFx 2.2; I have css-styling, but of course that does not help here. I could not find my issue addressed anywhere; this was the closest I've found.
I just want to say that I could not get "series.getNode().setStyle("-fx-stroke: " + color + ";")" to work. However, using "-fx-background" instead does work. I hope this helps someone.
I have a very dark background to my grids so I need to make all the markings in the headers white. I've been able to do that w/everything except the arrow icons in the AdvancedDataGrid. http://flexvenom.wordpress.com/2007/12/04/howto-setting-a-custom-sortitemrenderer-to-the-advanceddatagrid/ has a solution, but then it kills the sort sequence number. How can I just make everything in the header (except the background) white?
I'm running the 3.5 SDK.
In the end it was a lot simpler than what I was trying (having an item renderer draw the whole sort part) but it was still pretty complicated, in that I had to make 2 very light-weight renderers. I could have just had the sequence number just stay one colour, but decided to get a little fancy and have a mouse over colour and a normal colour.
The header renderer (ubicAdvancedDataGridHeaderRenderer.mxml) is:
<?xml version="1.0" encoding="utf-8"?>
<mx:AdvancedDataGridHeaderRenderer xmlns:mx="http://www.adobe.com/2006/mxml"
color="{ColourGlobals.TEXT_AGAINST_DARK}"
mouseOver="bMouseOver = true" mouseOut="bMouseOver = false">
<mx:Script><![CDATA[
public var bMouseOver:Boolean = false;
]]></mx:Script>
</mx:AdvancedDataGridHeaderRenderer>
then the sort renderer is:
package assets.GridTools {
import mx.controls.advancedDataGridClasses.AdvancedDataGridSortItemRenderer;
public final class ubiAdvancedDataGridSortItemRenderer extends AdvancedDataGridSortItemRenderer {
override protected function commitProperties():void {
super.commitProperties();
const oHeader:ubicAdvancedDataGridHeaderRenderer = owner as ubicAdvancedDataGridHeaderRenderer;
label.textColor = oHeader.bMouseOver ? ColourGlobals.DARK : ColourGlobals.TEXT_AGAINST_DARK;
}
}
}
Don't ask my why I made one Flex and the other AS. It works, so not being broke, I ain't gonna fix it.
