In-place editor for the graph. To control this editor, use mxGraph.invokesStopCellEditing, mxGraph.enterStopsCellEditing and mxGraph.escapeEnabled. If mxGraph.enterStopsCellEditing is true then ctrl-enter or shift-enter can be used to create a linefeed. The F2 and escape keys can always be used to stop editing. To customize the location of the textbox in the graph, override getEditorBounds as follows:
graph.cellEditor.getEditorBounds = function(state)
{
var result = mxCellEditor.prototype.getEditorBounds.apply(this, arguments);
if (this.graph.getModel().isEdge(state.cell))
{
result.x = state.getCenterX() - result.width / 2;
result.y = state.getCenterY() - result.height / 2;
}
return result;
};The textarea uses the mxCellEditor CSS class. You can modify this class in your custom CSS. Note: You should modify the CSS after loading the client in the page.
To only allow numeric input in the in-place editor, use the following code.
var text = graph.cellEditor.textarea;
mxEvent.addListener(text, 'keydown', function (evt)
{
if (!(evt.keyCode >= 48 && evt.keyCode <= 57) &&
!(evt.keyCode >= 96 && evt.keyCode <= 105))
{
mxEvent.consume(evt);
}
});To implement an initial value for cells without a label, use the emptyLabelText variable.
Resize of the textarea is disabled by default. If you want to enable this feature extend init and set this.textarea.style.resize = ‘’.
