In my C++ Builder Project i have a TFramedVertScrollBox (pnl_art_box) which dynamically gets TPanel's. I want to clear out all existing TPanel's before adding the "new" ones.
for(int i = 0; i < this->pnl_art_box->ComponentCount; i++)
{
// this here is where i dont find any solution ...
this->pnl_art_box->Components[i]->DestroyComponents();
}
for(int i = 0; i < i_article_amount;i++)
{
this->articlelistpanels[i] = new TPanel(this->pnl_art_box);
this->articlelistlabels[i] = new TLabel(this);
this->articlelistlabels[i]->Text = this->articlelist[i].get_name();
this->articlelistpanels[i]->Align = Fmx::Types::TAlignLayout::MostTop;
this->articlelistpanels[i]->AddObject(this->articlelistlabels[i]);
this->pnl_art_box->AddObject(this->articlelistpanels[i]);
}
At Google i only found very less help and none of them is in C++;
Would be nice, if someone could tell me, when i do wrong.
Sincerely Timo Treichel
I finally found it by myself.
The correct command had been:
for(int i = 1; i < this->pnl_art_box->ComponentCount; i++)
{
this->pnl_art_box->Components[i]->DisposeOf();
}

So I am having an interesting error which didn't exist in the previous Xcode Beta version. It pops up at runtime from this code: (Line 5 to be exact)
func removeDuplicates(urls: [NSString]) -> [NSString]{
var newURLs = [urls[0]]
for var i = 0; i < urls.count; i++ {
for var j = 0; j < newURLs.count; j++ {
if urls[i].isEqualToString(newURLs[j]) {
if j == newURLs.count-1 {
newURLs.append(urls[i])
}
} else {
j = newURLs.count
}
}
}
println(newURLs.debugDescription)
return newURLs
}
The errors are as follows:
objc[322]: Class _NSSwiftEnumeratorBase is implemented in both "MyAppFilePath.app"/Frameworks/libswift_stdlib_core.dylib and "MyAppFilePath.app"/Frameworks/libswiftCore.dylib. One of the two will be used. Which one is undefined.
There are about two dozen of those for different swift classes.
As I said there was not a problem here until I changed versions, I know some syntax changed but nothing in the release notes really pointed to such a thing.
Had the same issue, doing a Clean (Shift+Cmd+K) resolved it for me.
I am using a tee chart library in xamarin (Android). i am facing a problem to daynamic binding data in "Candle Chart"
The Sample Code Like this!
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
RequestWindowFeature(WindowFeatures.NoTitle);
SetContentView(Resource.Layout.CandleChart);
//InitializeComponent();
chart = new Steema.TeeChart.TChart(this.ApplicationContext);
chart.Zoom.Style = Steema.TeeChart.ZoomStyles.InChart;
Steema.TeeChart.Themes.BlackIsBackTheme myTheme = new Steema.TeeChart.Themes.BlackIsBackTheme(chart.Chart);
myTheme.Apply();
Type tmp = (Type)Steema.TeeChart.Utils.SeriesTypesOf[12];
Steema.TeeChart.Styles.Series series;
series = chart.Series.Add(tmp);
series.FillSampleValues(); /* Here i want to fill series with my data listed bellow */
chart.Aspect.View3D = Needs3D(chart[0]);
chart.Panel.Transparent = true;
SetContentView(chart);
}
now i want add series data manually
like :
currentItem.Data.Close
currentItem.Data.Open
currentItem.Data.High
currentItem.Data.Low
currentItem.Time
etc.. so, plz help me to achieve this ..
thanks, in advance

My Code Like as Bellow

DataSet_Obj.Tables["CandleTable"].Columns.Add(new DataColumn("Close", System.Type.GetType("System.Double")));
DataSet_Obj.Tables["CandleTable"].Columns.Add(new DataColumn("High", System.Type.GetType("System.Double")));
DataSet_Obj.Tables["CandleTable"].Columns.Add(new DataColumn("Low", System.Type.GetType("System.Double")));
for (int i = 0; i < resGraph.graphSymbol[0].CandleSticks.Length; i++)
{
DataRow_Obj = DataSet_Obj.Tables["CandleTable"].NewRow();
DataRow_Obj["Date"] = resGraph.graphSymbol[0].CandleSticks[i].CandleTime; //DateTime
DataRow_Obj["Low"] = resGraph.graphSymbol[0].CandleSticks[i].CandleData.Low; //Float
DataRow_Obj["Close"] = resGraph.graphSymbol[0].CandleSticks[i].CandleData.Close; //Float
DataRow_Obj["Open"] = resGraph.graphSymbol[0].CandleSticks[i].CandleData.Open; //Float
DataRow_Obj["High"] = resGraph.graphSymbol[0].CandleSticks[i].CandleData.High; //Float
DataSet_Obj.Tables["CandleTable"].Rows.Add(DataRow_Obj);
DataRow_Obj = null;
}
Tag_Serie_Candle = new Steema.TeeChart.Styles.Candle ();
chart.Series.Add(Tag_Serie_Candle);
chart.Aspect.View3D = Needs3D(chart[0]);
chart.Panel.Transparent = true;
try
{
Tag_Serie_Candle.DataSource = DataSet_Obj.Tables["CandleTable"]; /* here I got Error Like: "Cannot bind to non-supported datasource: CandleTable" */
Tag_Serie_Candle.OpenValues.DataMember = DataSet_Obj.Tables["CandleTable"].Columns["Open"].ToString();
Tag_Serie_Candle.CloseValues.DataMember = DataSet_Obj.Tables["CandleTable"].Columns["Close"].ToString();
Tag_Serie_Candle.DateValues.DataMember = DataSet_Obj.Tables["CandleTable"].Columns["Date"].ToString();
Tag_Serie_Candle.DateValues.DateTime = true;
Tag_Serie_Candle.HighValues.DataMember = DataSet_Obj.Tables["CandleTable"].Columns["High"].ToString();

Tag_Serie_Candle.CheckDataSource();
chartpie.AddView(chart, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MatchParent, ViewGroup.LayoutParams.MatchParent));

You should do something as in the examples here:

I have found that, at the present moment, this is not working. I added the defect (ID566) list to be fixed as soon as possible (now fixed, see update at the bottom of the reply). If you register at Steema Software's Bugzilla system, you will be able to be in the CC List and be notified about status updates. In the meantime you can manually read values from the DataSet using this code:
Tag_Serie_Candle.DateValues.DateTime = true;
for (int i = 0; i < DataSet_Obj.Tables["CandleTable"].Rows.Count; i++)
{
DataRow row = DataSet_Obj.Tables["CandleTable"].Rows[i];
DateTime dt = Convert.ToDateTime(row["Date"]);
Double open = Convert.ToDouble(row["Open"]);
Double high = Convert.ToDouble(row["High"]);
Double low = Convert.ToDouble(row["Low"]);
Double close = Convert.ToDouble(row["Close"]);
Tag_Serie_Candle.Add(dt, open, high, low, close);
}
UPDATE: As of 11th February 2014, the defect has been fixed. Anyone interested in testing the solution please let me know.
A have several views with WebViews on them. I need to make it in a coverFlowView. For that i make my views toImage, to put after on the coverFlow, but the issue is that i get images with webView not loaded... I tried to make setTimeout, but it doesn't help.
var cover = Titanium.UI.iOS.createCoverFlowView({
images: forflowImages
});
for (var k = start; k < cData.length; k++) {
r = Ti.UI.createView({});
for (var j = 0; j < child.objects.length; j++) {
tmp = Ti.UI.createWebView({
left : 10,
top : 10,
right : 10,
bottom : 10,
width : Ti.UI.FILL,
height : Ti.UI.SIZE,
willHandleTouches: true,
backgroundColor : '#fff2df',
});
tmp.html = obj.html;
no.add(tmp);
r.add(no);
}
}
r.addEventListener("load", function(e) {
blob = r.toImage();
});
forflowImages.push(blob);
}
cover.setImages(forflowImages);
With this code, coverFlowView doesn't have any views.
setTimeout(function() {
blob = r.toImage();
}, 500);
Also doesn't help, i have activity indicator on the page saved, content seems didn't have time to load before toImage function acted.
You are ordering things the wrong way, and you have multiple syntax errors, also you are listeneing for the load event on the wrong type of view, you shold be listeneing on the WebView, try this instead:
var forflowImages = [];
var container = // This should already be in the view stack somewhere
var cover = Titanium.UI.iOS.createCoverFlowView();
function loadListener(e) {
forflowImages.push(e.source.toImage());
if(forFlowImages.length == child.objects.length) {
// We have all the images for cover flow
cover.setImages(forflowImages);
}
}
var containerView = Ti.UI.createView();
for (var j = 0; j < child.objects.length; j++) {
var tmp = Ti.UI.createWebView({html : obj.html);
tmp.addEventListener("load", loadListener);
container.add(tmp);
tmp.repaint();
}
I removed some of your code that was syntactically incorrect and trimmed it down so it would be easy to understand. All this code does is add an event listener that handles the conversion of a webview to an image.
I have a code that draws a bunch of customized shapes from an xml... I want to make each shape select-able /de-selectable by changing the color of the object and changing backk all other colors when things change but my codes broken but i'm not getting any errors or anything it just doesn't work.
var graphicsShape
function drawLayer(layer){
for (var i =0; i < xmlDoc.getElementsByTagName("polygon").length; i++)
{
if (layer == xmlDoc.getElementsByTagName("polygon")[i].childNodes[0].attributes[4].value)
{ drawSegment(i);
}
}
}
// layer = index z
function drawSegment(a){
var vertexList = xmlDoc.getElementsByTagName("polygon")[a].childNodes;
var graphicsObject = new createjs.Graphics();
graphicsShape = new createjs.Shape(graphicsObject);
graphicsObject.setStrokeStyle(1);
graphicsObject.beginStroke(createjs.Graphics.getRGB(0,0,0));
graphicsObject.beginFill(createjs.Graphics.getRGB(255,0,0));
for(var i = 0; i < vertexList.length; i++){
graphicsObject.lineTo(vertexList[i].attributes[2].value, vertexList[i].attributes[3].value)
stage.addChild(graphicsShape);
}
segmentsArray.push(graphicsShape);
//createContainer(segmentsArray[i]);
}
function createArraysForSegments() {
for(var i=0; i <segmentsArray.length; i++){
segmentsData[i] = new Array;
}
}
function ColorChangeAddEventListener() {
for(var i = 0; i < segmentsArray.length; i++){
segmentsArray[i].addEventListener('click', colorChange(i));
}
}
function colorChange(index){
segmentsArray[index].graphics.beginFill('white');
stage.update();
}
i call the functions later
ColorChangeAddEventListener();
drawLayer(0);
stage.update();
if i type segmentsArray[0].alpha =0.5; it works for that shape, but when I put it in segmentsArray[0].addEventsListener('click', function){segmentsArray[0].alpha=0.5;}) that doesn't work
Just setting the beginFill won't affect the current shape, you will also have to segmentsArray[index].graphics.clear() and redraw the shape.
beginFill() is not the setter for a property but rather a command that affects subsequents commands, like drawRect() for example.
I'm trying to retrieve all fields of a Memo in blackberry device. At the moment I'm testing in my simulator OS 5.0. My code below:
StringBuffer sb = new StringBuffer();
BlackBerryMemo item = null;
while(memos!=null && memos.hasMoreElements()){
item = (BlackBerryMemo) memos.nextElement();
int[] fieldIds = item.getFields();
int id;
for(int index = 0; index < fieldIds.length; ++index)
{
id = fieldIds[index];
if(item.getPIMList().getFieldDataType(id) == PIMItem.STRING)
{
for(int j=0; j < item.countValues(id); ++j)
{
String value = item.getString(id, j);
sb.append(((PIMList) item).getFieldLabel(id) + " = " + value); //problem here
}
}
}
}
The problem I'm facing is that when the last line is executed, it throws ClassCastException. Can some one please help? Thanks a lot.
Sorry, such a silly question. I corrected the line of code to:
sb.append((item.getPIMList()).getFieldLabel(id) + " = " + value));
And it was solved. Thanks anyways.
