Usage

Minimal Example

<ngx-widget-grid [rows]="4" [columns]="5" [highlightNextPosition]="false"
                 [showGrid]="true" (widgetPositionChange)="onWidgetChange($event)">
  <ngx-widget [(position)]="{top: 2,left: 2,height: 1,width: 1}"
              [movable]="true" [resizable]="true">
    <div style="height:100%;width:100%; display:flex;">
      <div style="height:100%;width:100%; padding:10px; background-color: rgb(140, 198, 0);">
      </div>
    </div>
  </ngx-widget>
</ngx-widget-grid>

Minimal Example

Adding Traits

Widgets

position
<ngx-widget [(position)]="widget.position"...>

You can bind the position of the widget to data received from server so that even if the widget is moved, the new positions are always updated in the widget configuration.

movable
<ngx-widget [movable]="true" [(position)]="widget.position"...>

If movable is true, users will be able to move the respective widget.

Moving Widgets

resizable
<ngx-widget [resizable]="true" [(position)]="widget.position"...>

If resizable is true, users will be able to resize the respective widget.

Resizing Widgets

Optionally, you can limit the resize directions:

<ngx-widget [resizeDirections]="['NW', 'NE', 'E', 'SW']" [(position)]="widget.position"...>

Restricted Resizing

swapOnMove
<ngx-widget [swapOnMove]="true" [(position)]="widget.position"...>

If swapOnMove is true, dragged widget will swap position and size with the widget over which the current one is dropped. Default is false which means, widget will be placed in the nearest available area.

Grid: Options

showGrid (default: false)
<ngx-grid columns="20" rows="15" [showGrid]="true">

Toggles the gridlines.

Gridlines Enabled

highlightNextPosition (default: false)
<ngx-grid columns="20" rows="15" [highlightNextPosition]="true">

Highlights the largest free area in the grid, if any. This area will be automatically assigned to the next widget with a falsy or conflicting position.

Highlight Next Position (1/2) Highlight Next Position (2/2)

Events

gridFull

The grid emits gridFullevent as true (when grid has been fully occupied) or false when there is still some space left in the grid, so that you can e.g. enable/disable UI elements accordingly.

<ngx-grid columns="20" rows="15" (gridFull)="onGridFull($event)">
function onGridFull(isGridFull) {
    if(isGridFull){
        ...
        //make add widget button disabled
        ...
    }else{
        ...
        //make add widget button enabled
        ...
    }
}
widgetPositionChange

Emitted whenever the position of a widget is changed. The event comes with an attached object argument, which contains the affected widget's index and its newPosition.

<ngx-grid columns="20" rows="15" (widgetPositionChange)="onWidgetChange($event)">

Functions

getNextPosition

getNextPosition is a function you could call to get details about the next available position that is being highlighted as part of highlightNextPosition.
