I am using CELLS_ADDED event to check if shape added in the graph.
How can I get the label for the shape?
My code is
Graph.prototype.addListener(mxEvent.CELLS_ADDED, function(sender, evt)
{
var e = evt.getProperty('event'); // mouse event
var cell = evt.getProperty('cell'); // cell may be null
var tex = evt.getProperty('text');
if (cell != null)
{
// Do something useful with cell and consume the event
evt.consume();
}
});
I'm not sure what you asking for but maybe what you want is this:
var label = cell.getValue();

How can I make the navtitle curve along the path of the slice and wrap the text if it's long.
Image of the wheel above
In long text, use '\n' in the title for wrap.
wheel.createWheel(["Long\ntext"]);
Currently, the navtitle curve along the path is an RC feature, so please use the source code instead of the last release.
You can find the new properties in this CodePen: https://codepen.io/softwaretailoring/pen/RQYzWm
var piemenu = new wheelnav("wheelDiv");
// New properties in wheelnav.js v1.8.0
piemenu.titleCurved = true;
piemenu.titleCurvedClockwise = false;
piemenu.titleCurvedByRotateAngle = false;
Unfortunately, the two above properties don't work together. :(
UPDATE: There is a way to achieve your needs. You can use two wheels on each other.
var piemenu = new wheelnav("wheelDiv");
setMenu(piemenu); // Set common properties
piemenu.titleRadiusPercent = 0.65; // Positioning first title
piemenu.markerEnable = true;
piemenu.slicePathFunction = slicePath().DonutSlice;
piemenu.sliceClickablePathFunction = slicePath().DonutSlice;
piemenu.titleHoverAttr = { fill: "#333" };
piemenu.createWheel(["Hello", "world!", "-------"]);
var piemenu2 = new wheelnav("wheelDiv2", piemenu.raphael);
setMenu(piemenu2); // Set common properties
piemenu2.wheelRadius = 520; // Positioning second title
piemenu2.slicePathFunction = slicePath().NullSlice; // There is no slice, only title
piemenu2.createWheel(["Bello", "space!", "*******"]);
// Link navigateFunctions to each other
for (var i = 0; i < piemenu.navItems.length; i++) {
piemenu.navItems[i].navigateFunction = function () {
piemenu2.navigateWheel(Math.abs(this.itemIndex));
}
}
for (var i = 0; i < piemenu2.navItems.length; i++) {
piemenu2.navItems[i].navigateFunction = function () {
piemenu.navigateWheel(Math.abs(this.itemIndex));
}
}

I am developing a metro app where , I want to have a customized bar slide when the user clicks on something in the screen.
This is what i am talking about :-
--------------
| | |
| | | <----
| | |
---------------
main screen side
bar
In this side bar i want have some simple controls like image and text block etc..
1) How can i do this , any help would be appreciated
2) Its not against metro principles right ?
You could try to leverage a flyout like the settings flyout. You might want to look at Callisto.
You could otherwise include a Xaml element that above all others and toggle it's visibility along with a positioning right on the screen. How to position depends on what root element you're using. For positioning an element in a canvas add Canvas.Right="0" to the child element.
You can use PopUp.
have a look at this example,
http://code.msdn.microsoft.com/windowsapps/App-settings-sample-1f762f49
you can use following helper
WinRT Flyout Helper
public class FlyoutHelper
{
protected Popup m_Popup = new Popup();
public Popup Show(Popup popup, FrameworkElement button, double offset = 35d)
{
if (popup == null)
throw new Exception("Popup is not defined");
m_Popup = popup;
if (button == null)
throw new Exception("Button is not defined");
if (double.IsNaN(offset))
throw new Exception("Offset is not defined");
var _Child = popup.Child as FrameworkElement;
if (_Child == null)
throw new Exception("Popup.Child is not defined");
if (double.IsNaN(_Child.Height))
throw new Exception("Popup.Child.Height is not defined");
if (double.IsNaN(_Child.Width))
throw new Exception("Popup.Child.Width is not defined");
// get position of the button
var _Page = Window.Current.Content as Page;
var _Visual = button.TransformToVisual(_Page);
var _Point = _Visual.TransformPoint(new Point(0, 0));
var _Button = new
{
Top = _Point.Y,
Left = _Point.X,
Width = button.ActualWidth,
Height = button.ActualHeight,
};
// determine location
var _TargetTop = (_Button.Top + (_Button.Height / 2)) -
_Child.Height - offset;
var _TargetLeft = (_Button.Left + (_Button.Width / 2)) -
(_Child.Width / 2);
if ((_TargetLeft + _Child.Width) > Window.Current.Bounds.Width)
_TargetLeft = Window.Current.Bounds.Width - _Child.Width - offset;
if (_TargetLeft < 0)
_TargetLeft = offset;
// setup popup
popup.VerticalOffset = _TargetTop;
popup.HorizontalOffset = _TargetLeft;
// add pretty animation(s)
popup.ChildTransitions = new TransitionCollection
{
new EntranceThemeTransition
{
FromHorizontalOffset = 0,
FromVerticalOffset = 20
}
};
// setup
m_Popup.IsLightDismissEnabled = true;
m_Popup.IsOpen = true;
// handle when it closes
m_Popup.Closed -= popup_Closed;
m_Popup.Closed += popup_Closed;
// handle making it close
Window.Current.Activated -= Current_Activated;
Window.Current.Activated += Current_Activated;
// return
return m_Popup;
}
protected void Current_Activated(object sender, WindowActivatedEventArgs e)
{
if (m_Popup == null)
return;
if (e.WindowActivationState == CoreWindowActivationState.Deactivated)
m_Popup.IsOpen = false;
}
protected void popup_Closed(object sender, object e)
{
Window.Current.Activated -= Current_Activated;
if (m_Popup == null)
return;
m_Popup.IsOpen = false;
}
}
For this you can use CharmFlyout.
Here is the sample code http://code.msdn.microsoft.com/windowsapps/CharmFlyout-A-Metro-Flyout-25fe53b6
I'm using ExtendScript for scripting Adobe Illustrator. I was wondering if there was a sneaky way or a script available to programmatically capture and then replicate a path shape, sort of JavaScript's .toSource() equivalent.
Thanks
Try this:
main();
function main(){
var doc = app.activeDocument; // get the active doc
var coords = new Array(); // make a new array for the coords of the path
var directions = new Array();
var sel = doc.selection[0];// get first object in selection
if(sel == null) {
// check if something is slected
alert ("You need to sevlect a path");
return;
}
var points = sel.pathPoints;// isolate pathpoints
// loop points
for (var i = 0; i < points.length; i++) {
// this could be done in one lines
// just to see whats going on line like
//~ coords.push(new Array(points[i].anchor[0],points[i].anchor[1]));
var p = points[i]; // the point
var a = p.anchor; // his anchor
var px = a[0];// x
var py = a[1]; // y
var ldir = p.leftDirection;
var rdir = p.rightDirection;
directions.push(new Array(ldir,rdir));
coords.push(new Array(px,py));// push into new array of array
}
var new_path = doc.pathItems.add(); // add a new pathitem
new_path.setEntirePath(coords);// now build the path
// check if path was closed
if(sel.closed){
new_path.closed = true;
}
// set the left and right directions
for(var j = 0; j < new_path.pathPoints.length;j++){
new_path.pathPoints[j].leftDirection = directions[j][0];
new_path.pathPoints[j].rightDirection = directions[j][1];
}
}
Is it possible that the axis scale outside the graph could be scale using the mouse event "mouse_down and hold" and move up or down in y-axis the same with the x-axis move left or right? ex. when I trigger MouseDownEvent and hold the x-axis scale 0.6 or at the space along with that scale and move it to the right, scale should scroll depend in the chartfraction? could you post an example? Thanks in advance!
Separately panning and zooming Y axises can be achieved using the mouse events of ZedGraph: MouseDownEvent, MouseMoveEvent, MouseUpEvent and MouseWheel events (credits go to a colleague of mine).
It works with multiple GraphPanes and multiple Y axises.
The MouseMoveEvent is used to shift the Min and the Max of an Y axis when the mouse is moved while its button is pressed. If not, it is used to get the reference of the Y axis object the mouse is hovering on.
The MouseDownEvent is used to initiate an axis pan operation.
The MouseWheel is used to perform a zoom on an Y axis.
And the MouseUpEvent is used to clean things when zooming and panning operations are finished.
Here is the code :
// The axis that is currently hovered by the mouse
YAxis hoveredYAxis;
// The graphpane that contains the axis
GraphPane foundPane;
// The scale of the axis before it is panned
double movedYAxisMin;
double movedYAxisMax;
// The Y on the axis when the panning operation is starting
float movedYAxisStartY;
void z_MouseWheel(object sender, MouseEventArgs e)
{
if (hoveredYAxis != null)
{
var direction = e.Delta < 1 ? -.05f : .05f;
var increment = direction * (hoveredYAxis.Scale.Max - hoveredYAxis.Scale.Min);
var newMin = hoveredYAxis.Scale.Min + increment;
var newMax = hoveredYAxis.Scale.Max - increment;
hoveredYAxis.Scale.Min = newMin;
hoveredYAxis.Scale.Max = newMax;
foundPane.AxisChange();
z.Invalidate();
}
}
bool z_MouseUpEvent(ZedGraphControl sender, MouseEventArgs e)
{
hoveredYAxis = null;
return false;
}
bool z_MouseMoveEvent(ZedGraphControl sender, MouseEventArgs e)
{
var pt = e.Location;
if (e.Button == System.Windows.Forms.MouseButtons.Left)
{
if (hoveredYAxis != null)
{
var yOffset = hoveredYAxis.Scale.ReverseTransform(pt.Y) - hoveredYAxis.Scale.ReverseTransform(movedYAxisStartY);
hoveredYAxis.Scale.Min = movedYAxisMin - yOffset;
hoveredYAxis.Scale.Max = movedYAxisMax - yOffset;
sender.Invalidate();
return true;
}
}
else
{
var foundObject = findZedGraphObject(null);
hoveredYAxis = foundObject as YAxis;
if (hoveredYAxis != null)
{
z.Cursor = Cursors.SizeNS;
return true;
}
else
{
if (z.IsShowPointValues)
{
z.Cursor = Cursors.Cross;
return false;
}
else
{
z.Cursor = Cursors.Default;
return true;
}
}
}
return false;
}
bool z_MouseDownEvent(ZedGraphControl sender, MouseEventArgs e)
{
if (e.Button == System.Windows.Forms.MouseButtons.Left)
{
if (hoveredYAxis != null)
{
movedYAxisStartY = e.Location.Y;
movedYAxisMin = hoveredYAxis.Scale.Min;
movedYAxisMax = hoveredYAxis.Scale.Max;
return true;
}
}
return false;
}
This is a helper that factorizes a bit the object find operations of ZedGraph.
object findZedGraphObject(GraphPane pane = null)
{
var pt = zgc.PointToClient(Control.MousePosition);
if (pane == null)
{
foundPane = zgc.MasterPane.FindPane(pt);
if (foundPane != null)
{
object foundObject;
int forget;
using (var g = zgc.CreateGraphics())
if (foundPane.FindNearestObject(pt, g, out foundObject, out forget))
return foundObject;
}
}
return null;
}
If I understand your question correctly, here's my response:
zedgraph has got an in-built function called "Pan", you could change the scale of x & y axis.
Place the cursor within the 'chart area'
Hold the 'ctrl' button & move the mouse towards x & y directions to change the scale.
you could get back to original state by 'Un-Pan' (Context Menu)
Cheers..:)
Do You want to create a ScrollBar?
zedGraphControl1.IsShowHScrollbar = true;
//Set borders for the scale
zedGraphControl1.GraphPane.XAxis.Scale.Max = Xmax;
zedGraphControl1.GraphPane.XAxis.Scale.Min = Xmin;
I want to disable one specific row in datagrid in following manner:
1) Highlight one row with a different color
2) Disable checkbox/radio button selection of that row
3) Disable inline editing of cells present in that row but allow inline editing for other rows.
Pls. help if you have any ideas.
You can use a combination of the following functions to extract stuff
// as example, one of youre items uses identifier:'id' and 'id:10'
var identifier = '10';
var item = store._arrayOfTopLevelItems[10]; // you probably have this allready
var index = grid.getItemIndex(item); // find which index it has in grid
var rowNode = grid.getRowNode(index); // find a DOM element at that index
You will have the <div> as rowNode, it contains a table with cells (as many as you got columns). Set its background-color
The checkbox thing, you will prly know which cell-index it has
var cellNode = dojo.query('td[idx='+cellIndex+']', rowNode)[0];
// with cellType Bool, td contains an input
var checkbox = cellNode.firstChild;
Editing is another store really.. works in focus handlers. To override it, you must keep like an array of rows which you dont want editable (allthough the cell.editable == true).
function inarray(arr, testVal) {
return dojo.some(arr, function(val) { return val == testVal }).length > 0
}
grid.setNonEditable = function (rowIndex) {
if(! inarray(this.nonEditable,rowIndex) )
this.nonEditable.push(rowIndex);
}
grid.setEditable = function (rowIndex) {
this.nonEditable = dojo.filter(this.nonEditable, function(val) { return val != rowIndex; });
}
var originalApply = grid.onApplyEdit
grid.onApplyEdit = function(inValue, inRowIndex) {
if(! inarray(this.nonEditable,inRowIndex) )
originalApply.apply(this, arguments);
}
If you are using dojox.grid.DataGrid you can use canEdit function to disable row editing or cell editing :
grid = new dojox.grid.DataGrid({
canEdit: function(inCell, inRowIndex) {
var item = this.getItem(inRowIndex);
var value = this.store.getValue(item, "name");
return value == null; // allow edit if value is null
}
}
