Zooming an Panning a Gantt-chart using the mouse

Hi,

sorry to be almost "spamming" but we need some answers pretty soon ... Is there a way to zoom using the mouse and when in zoom (so not scale 1) implement the right-click in a manner that panning becomes possible ?

If so, could you give some tips (or working code :-) ) to get this done ?

Thanks,

Wim

Hi

I need to change the color of the box while mouse is drawing on the chart.

Dim xAxis As IAdvanceAxis = DirectCast(e.Grid("X"), IAdvanceAxis)

Dim yAxis As IAdvanceAxis = DirectCast(e.Grid("Y"), IAdvanceAxis)

Dim width As Integer = Math.Abs(m_endPoint.X - m_startPoint.X)

Dim height As Integer = Math.Abs(m_endPoint.Y - m_startPoint.Y)

Dim box As New Primitives.Box(m_startPoint, width, height)

Thanks

Where can I find InteractionTool ??

I can't get the Chartsamples to work, it crashes giving following error :

************** JIT-foutopsporing **************
Als u JIT-foutopsporing wilt inschakelen, moet in het configuratiebestand voor deze
toepassing of computer (machine.config) de waarde
jitDebugging in het gedeelte system.windows.forms zijn ingesteld.
De toepassing moet ook zijn gecompileerd terwijl foutopsporing
was ingeschakeld.

Bijvoorbeeld:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

Wanneer JIT-foutopsporing is ingeschakeld, worden onverwerkte uitzonderingen
naar het JIT-foutopsporingsprogramma gestuurd dat op de computer is geregistreerd
en worden niet door dit dialoogvenster verwerkt.

You can try using:

public class PanningTool : InteractionTool

{
private Point prevPoint;
private AxisAppearance axisApp;
private Axis axis;
/// <summary>

/// Initializes a new instance of the <see cref="PanningTool"/> class.

/// </summary>

/// <param name="ultraChart">The ultra chart.</param>
public PanningTool(UltraChart ultraChart): base(ultraChart)
{

}

/// <summary>

/// Determines whether this tool can start.

/// </summary>

/// <returns>

/// <c>true</c> if this tool can start; otherwise, <c>false</c>.

/// </returns>
public override bool CanStart()
{
if (this.LastInput.MouseEventArgs.Button == MouseButtons.Right)
{
return true;
}
return false;
}

/// <summary>

/// Called when this tool starts.

/// </summary>
public override void Start()
{
GridLayer gridLayer = this.ChartCore.GetGridLayer() as GridLayer;
this.axis = gridLayer.Grid["X"] as Axis;
this.axisApp = (AxisAppearance)this.axis.GetAppearance();
this.prevPoint = this.LastInput.ViewPoint;
System.Windows.Forms.Cursor.Current = Cursors.Hand;
}

/// <summary>

/// Called when this tool is started and the mouse is moved.

/// </summary>
public override void MouseMove()
{
base.MouseMove();
int dx = this.LastInput.ViewPoint.X - prevPoint.X;
double correction = -64;
double coef = (axis.MapRange + correction) * (1 - axis.Scale);
double scrollOffset = dx / coef;
if (double.IsNaN(scrollOffset))
return;
double d = axisApp.ScrollScale.Scroll + scrollOffset;
if (d < 0)
{

d = 0;

}
if (d > 1)
{

d = 1;

}

axisApp.ScrollScale.Scroll = d;
this.prevPoint = this.LastInput.ViewPoint;this.InvalidateView(CacheLevel.ImageLevelCache);
}

/// <summary>

/// Called when this tool stops.

/// </summary>
public override void Stop()
{
System.Windows.Forms.Cursor.Current = Cursors.Default;base.Stop();
}

}

...

PanningTool panningTool = new PanningTool(this.ultraChart1);

this.ultraChart1.AddMouseDownTool(panningTool);
