I am programmatically drawing a flowchart using Java UNO Runtime Reference in which I want to display grid Lines permanently.Using following code I was able to display the Grid Lines but they are toggled ON and OFF alternately when the code executes.
XModel xModel = (XModel) UnoRuntime.queryInterface(XModel.class, xDrawDoc);
XController xController = xModel.getCurrentController();
XDispatchProvider xDisp = UnoRuntime.queryInterface(XDispatchProvider.class, xController);
XMultiComponentFactory xMCF = xContext.getServiceManager();
Object dispatchHelper = xMCF.createInstanceWithContext("com.sun.star.frame.DispatchHelper", xContext);
XDispatchHelper xDispatchHelper = UnoRuntime.queryInterface(XDispatchHelper.class, dispatchHelper);
PropertyValue[] navigatorDesc = new PropertyValue[1];
navigatorDesc[0] = new PropertyValue();
navigatorDesc[0].Name = "GridVisible";
navigatorDesc[0].Value = true;
xDispatchHelper.executeDispatch(xDisp, ".uno:GridVisible" , "", 0, navigatorDesc);
I want to permanently show Grid Lines.How can I achieve this using Java.Pls suggest. If there is any way of checking whether the Grid Lines are ON(any method which could return a boolean value), this could also be a useful approach.

I am new in ArcGis. I came across a requirement that I need a command on the ArcGis Toolbar. On click the command, a Windows Form will open and there one region selector button is there. upon clicking on the button, the current Form UI must be minimized and the user will be allowed to draw a polygon. Can you please help on how to do that. Here is the code. I took normal windows button and wrote the below code in the click event.
_application = ((IApplication)_hookHelper.Hook);
IMxDocument pMxDoc = (IMxDocument)_application.Document;
IMap pMap = (IMap)pMxDoc.FocusMap;
IActiveView pActiveView = (IActiveView)pMap;
if (pActiveView == null)
{
return;
}
//// Changing the state of the Window.
if (this.WindowState == FormWindowState.Normal || this.WindowState == FormWindowState.Maximized)
{
this.WindowState = FormWindowState.Minimized;
// this.Hide();
}
ESRI.ArcGIS.Display.IScreenDisplay screenDisplay = pActiveView.ScreenDisplay;
// Constant
screenDisplay.StartDrawing(screenDisplay.hDC, (System.Int16)ESRI.ArcGIS.Display.esriScreenCache.esriNoScreenCache); // Explicit Cast
ESRI.ArcGIS.Display.IRgbColor rgbColor = new ESRI.ArcGIS.Display.RgbColorClass();
rgbColor.Blue = 111;
ESRI.ArcGIS.Display.IColor color = rgbColor; // Implicit Cast
ESRI.ArcGIS.Display.ISimpleFillSymbol simpleFillSymbol = new ESRI.ArcGIS.Display.SimpleFillSymbolClass();
simpleFillSymbol.Color = color;
ESRI.ArcGIS.Display.ISymbol symbol = simpleFillSymbol as ESRI.ArcGIS.Display.ISymbol; // Dynamic Cast
ESRI.ArcGIS.Display.IRubberBand rubberBand = new ESRI.ArcGIS.Display.RubberRectangularPolygonClass();
// ESRI.ArcGIS.Display.IRubberBand rubberBand = new ESRI.ArcGIS.Display.RubberPolygonClass();
ESRI.ArcGIS.Geometry.IGeometry geometry = rubberBand.TrackNew(screenDisplay, symbol);
screenDisplay.SetSymbol(symbol);
screenDisplay.DrawPolygon(geometry);
screenDisplay.FinishDrawing();
I am also not getting any mouse event and the UI is not minimized while starting drawing the polygon. Can anyone please help.
Have we check the white paper for ArcGIS runtime SDK for .Net?

In my C# Form I have a Label that displays a download percentage in the download event:
this.lblprg.Text = overallpercent.ToString("#0") + "%";
The Label control's BackColor property is set to be transparent and I want it to be displayed over a PictureBox. But that doesn't appear to work correctly, I see a gray background, it doesn't look transparent on top of the picture box. How can I fix this?
The Label control supports transparency well. It is just that the designer won't let you place the label correctly. The PictureBox control is not a container control so the Form becomes the parent of the label. So you see the form's background.
It is easy to fix by adding a bit of code to the form constructor. You'll need to change the label's Parent property and recalculate it's Location since it is now relative to the picture box instead of the form. Like this:
public Form1() {
InitializeComponent();
var pos = label1.Parent.PointToScreen(label1.Location);
pos = pictureBox1.PointToClient(pos);
label1.Parent = pictureBox1;
label1.Location = pos;
label1.BackColor = Color.Transparent;
}
Looks like this at runtime:
Another approach is to solve the design-time problem. That just takes an attribute. Add a reference to System.Design and add a class to your project, paste this code:
using System.ComponentModel;
using System.Windows.Forms;
using System.Windows.Forms.Design; // Add reference to System.Design
[Designer(typeof(ParentControlDesigner))]
class PictureContainer : PictureBox {}
You can just use
label1.Parent = pictureBox1;
label1.BackColor = Color.Transparent; // You can also set this in the designer, as stated by ElDoRado1239
You can draw text using TextRenderer which will draw it without background:
private void pictureBox1_Paint(object sender, PaintEventArgs e)
{
TextRenderer.DrawText(e.Graphics,
overallpercent.ToString("#0") + "%",
this.Font,
new Point(10, 10),
Color.Red);
}
When overallpercent value changes, refresh pictureBox:
pictureBox1.Refresh();
You can also use Graphics.DrawString but TextRenderer.DrawText (using GDI) is faster than DrawString (GDI+)
Also look at another answer here and DrawText reference here
For easy for your design.
You can place your label inside a panel. and set background image of panel is what every image you want. set label background is transparent
After trying most of the provided solutions without success, the following worked for me:
label1.FlatStyle = FlatStyle.Standard
label1.Parent = pictureBox1
label1.BackColor = Color.Transparent
You most likely not putting the code in the load function. the objects aren't drawn yet if you put in the form initialize section hence nothing happens.
Once the objects are drawn then the load function runs and that will make the form transparents.
private void ScreenSaverForm_Load(object sender, EventArgs e)
{
label2.FlatStyle = FlatStyle.Standard;
label2.Parent = pictureBox1;
label2.BackColor = Color.Transparent;
}
One way which works for everything, but you need to handle the position, on resize, on move etc.. is using a transparent form:
Form form = new Form();
form.FormBorderStyle = FormBorderStyle.None;
form.BackColor = Color.Black;
form.TransparencyKey = Color.Black;
form.Owner = this;
form.Controls.Add(new Label() { Text = "Hello", Left = 0, Top = 0, Font = new Font(FontFamily.GenericSerif, 20), ForeColor = Color.White });
form.Show();
Using Visual Studio with Windows Form you may apply transparency to labels or other elements by adding using System.Drawing; into Form1.Designer.cs This way you will have Transparency available from the Properties panel ( in Appearance at BackColor ). Or just edit code in Designer.cs this.label1.BackColor = System.Drawing.Color.Transparent;

I'm implementing a Pie Chart in Swift for iOS using ios-charts, and have chosen to customize the legend. Of note, the chart is displayed within a cell of a UICollectionView. The problem is that on first display, the custom legend content is not being displayed. Instead, I get legend content generated from the data.
If I scroll the view off-screen, and then scroll it back onto the screen, the proper custom legend is displayed. So, I'm guessing that I need to force a redraw/relayout/re-something after setting my custom legend. I haven't figured out how to do that. Does anyone have an idea? Am I completely missing something? Thanks!
Chart on initial display - data-generated (wrong) legend
Chart after scrolling off and back onto the screen - (proper legend)
Here's my code for drawing this chart:
func initChart(pieChart: PieChartView) {
numFormatter.maximumFractionDigits = 0
pieChart.backgroundColor = UIColor.whiteColor()
pieChart.usePercentValuesEnabled = false
pieChart.drawHoleEnabled = true
pieChart.holeTransparent = true
pieChart.descriptionText = ""
pieChart.centerText = "30%\nComplete"
pieChart.data = getMyData()
// Setting custom legend info, called AFTER setting data
pieChart.legend.position = ChartLegend.ChartLegendPosition.LeftOfChartCenter
pieChart.legend.colors = [clrGreenDk, clrGold, clrBlue]
pieChart.legend.labels = ["Complete","Enrolled","Future"]
pieChart.legend.enabled = true
}
func getMyData() -> ChartData {
var xVals = ["Q201","R202","S203","T204","U205", "V206"]
var courses: [ChartDataEntry] = []
courses.append(ChartDataEntry(value: 3, xIndex: 0))
courses.append(ChartDataEntry(value: 3, xIndex: 1))
courses.append(ChartDataEntry(value: 4, xIndex: 2))
courses.append(ChartDataEntry(value: 4, xIndex: 3))
courses.append(ChartDataEntry(value: 3, xIndex: 4))
courses.append(ChartDataEntry(value: 3, xIndex: 5))
let dsColors = [clrGreenDk, clrGreenDk, clrBlue, clrBlue, clrGold, clrGold]
let pcds = PieChartDataSet(yVals: courses, label: "")
pcds.sliceSpace = CGFloat(4)
pcds.colors = dsColors
pcds.valueFont = labelFont!
pcds.valueFormatter = numFormatter
pcds.valueTextColor = UIColor.whiteColor()
return ChartData(xVals: xVals, dataSet: pcds)
}
Update 4/30/2015
Based on discussion with author of MPAndroidChart (on which ios-charts is based), it appears there is not a point in the chart display lifecycle where one can override the legend on "first draw". Basically, the chart is rendered when it is created, no matter what. If you set data on the chart, the chart uses that data to create the legend and then renders. It isn't possible to change the legend between the point of setting data, and the point of chart rendering.
setNeedsDisplay()
Potentially, one can wait for the chart to render, update the legend, and then call chart.setNeedsDisplay() to signal the chart to redraw. Sadly, there's a timing problem with this. If you call this method immediately after rendering the chart, it either doesn't fire or (more likely) it fires too soon and is effectively ignored. In my code, placing this call within viewDidLoad or viewDidAppear had no effect. However...
Building the same chart in Java for Android (using MPAndroidChart) results in the same issue. After messing around for a bit, I noted that if I called the chart.invalidate() after a delay (using Handler.postDelayed()), it would fire properly. It turns out a similar approach works for ios-charts on iOS.
If one uses GCD to delay the call to setNeedsDisplay(), for even a few milliseconds after the rendering, it seems to do the trick. I've added the following code immediately after initializing the chart's view in my ViewController ("cell" is the UICollectionViewCell containing the chart view):
delay(0.05) {
cell.pieChartView.legend.colors = [self.clrGreenDk, self.clrGold, self.clrBlue]
cell.pieChartView.legend.labels = ["Complete","Enrolled","Future"]
// Re-calc legend dimensions for proper position (Added 5/2/2015)
cell.pieChartView.legend.calculateDimensions(cell.pieChartView.labelFont!)
cell.pieChartView.setNeedsDisplay()
}
Using the awesome "delay" method from this SO post: https://stackoverflow.com/a/24318861
Obviously, this is a nasty hack, but it seems to do the trick. I'm not sure I like the idea of using this hack in production, though.
For any Android folk who stumble on this post:
The following code achieves the same effect using MPAndroidChart:
// Inside onCreate()
pie = (PieChart) findViewById(R.id.chart1);
configPieChart(pie);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
String[] legLabels = new String[]{"Complete","Enrolled","Future"};
ArrayList<Integer> legColors = new ArrayList<Integer>();
legColors.add(blue);
legColors.add(gold);
legColors.add(green);
pie.getLegend().setPosition(Legend.LegendPosition.LEFT_OF_CHART_CENTER);
pie.getLegend().setColors(legColors);
pie.getLegend().setLabels(legLabels);
pie.invalidate();
}
}, 20);
I am the author of ios-charts, and we're working on features for customizing the legend data, without those "hacks".
In the latest commits to ios-charts, you can already see extraLabels and extraColors properties that add extra lines to the legend, and a setLegend function that allows you to set a custom data entirely.
This will soon be added to the Android version as well.
Enjoy :-)
Any help with this would be much appreciated.
I am trying to build an app in Windows 8 using xaml and vb.
To test the process of adding a path dynamically to the UI I have created a class that draws a circle using a path (code below). The code fires when a button is tapped/clicked.
The circle then appears briefly near the centre of the screen but then disappears.
If I then count the children on the grid, the circle is counted. Its just not visible.
I'd like to understand what is happening and stop the circle from disappearing.
Dim path As New Windows.UI.Xaml.Shapes.Path
Dim rectG As New EllipseGeometry
rectG.Center = New Point(500, 500)
rectG.RadiusX = 100
rectG.RadiusY = 100
path.Data = rectG
path.Stroke = New SolidColorBrush(Windows.UI.Colors.LightGreen)
path.StrokeThickness = 1
path.Fill = New SolidColorBrush(Windows.UI.Colors.LightGreen)
path.Name = "TestName"
_TargetGrid.Children.Add(path)
Finally figured it out. I needed to set the column and row span property.
On the test I did it using the code although in a proper app it would probably make sense to use some kind of predetermined styling.
However, here is the code I added:
path.SetValue(Grid.ColumnSpanProperty, 5)
path.SetValue(Grid.RowSpanProperty, 5)
I'm trying to update a windows 8 application from the Developer Preview to the Consumer Preview. It seems there's been a few changes. This code used to work:
var myDataSource = new WinJS.UI.ArrayDataSource(array)
var basicListView = WinJS.UI.getControl(document.getElementById("basicListView"));
basicListView.dataSource = myDataSource;
Now, there is no WinJS.UI.getControl method and no ArrayDataSource. This is my code:
var dataList = new WinJS.Binding.List(array);
var list = document.getElementById("basicListView");
list.itemDataSource = dataList.dataSource;
but it does nothing (except add a property to a DOM element that is ignored). Any ideas what I'm missing?
Got it. To get the control you now use the winControl property of the element:
var list = document.getElementById("basicListView").winControl;
Setting the itemDataSource works a treat.
