<template>
<div style="height: 500px; width: 500px; border: 1px solid red; position: relative;">
<vue-draggable-resizable :w="100" :h="100" @dragging="onDrag" @resizing="onResize" :parent="true">
<p>Hello! I'm a flexible component. You can drag me around and you can resize me.<br>
X: {{ x }} / Y: {{ y }} - Width: {{ width }} / Height: {{ height }}</p>
</vue-draggable-resizable>
</div>
</template>
<script>

export default {
data: function () {
return {
width: 0,

}
},
methods: {
onResize: function (x, y, width, height) {
this.x = x

Default: handle
Used to set the custom common class
of each handle element. This way you can style each handle individually using the selector <your class>-<handle code>
, where handle code
identifies one of the handles provided by the handle
prop.
So for example, this component:
<vue-draggable-resizable class-name-handle="my-handle-class"></vue-draggable-resizable>
renders the following:
<div ...>
<div class="my-handle-class my-handle-class-tl"></div>
<div class="my-handle-class my-handle-class-tm"></div>
<div class="my-handle-class my-handle-class-tr"></div>
[...]
</div>
Type: Number|Array
Required: false
Default: 1
The scale
prop controls the scale property when the CSS 3 scale transformation is applied to one of the parent elements. If not provided the default value is 1.
<vue-draggable-resizable :scale="0.5">
<vue-draggable-resizable :scale="[0.5, 0.4]">
Type: Boolean
Required: false
Default: true
By default, the component adds the style declaration 'user-select:none'
to itself to prevent text selection during drag. You can disable this behaviour by setting this prop to false
.

Type: Boolean
Required: false
Default: false
By default, the browser's native drag and drop funcionality (usually used for images and some other elements) is disabled, as it may conflict with the one provided by the component. If you need, for whatever reason, to have this functionality back you can set this prop to true
.
<vue-draggable-resizable :enable-native-drag="true">
Type: Boolean
Required: false
Default: false
Determines if the component should be active or not. The prop reacts to changes and also can be used with the sync

You can style the component using appropriate class names passed as props to the component. Moreover you can replace the default styles for the handles, provided in the source file vue-draggable-resizable.css
, but you should take care to define position and size for them. The default classes for handles are handle
and handle-tl
, handle-br
and so on.
The component also provides named slots for each handle, so you can use your markup inside each one.
