Question

Custom Widget with SubWidget

Hello Community,

 

we decided to use some more custom CSS in our UI and would like to leverate the bootstrap CSS.
For this purpose I am currently developing some Custom Widgets that should enhance our layouts
and look & feel.

 

The idea is to use the Bootstrap Card Class and make it an container widget, that by itself contains a

flexcontainer.  So it should have the structure:
<div class="card">
 <div class="card-header">Header</div>
 <div class="card-body">
 <!-- Create Flex Container here -->
 </div>
</div>
I had a closer look at the tabsv2-Widget how to do this and created a simple widget with similar behaviour (attached zip), but I have a massivie issue with the placement of the SubWidget.

 

The Code creates final HTML like this:

<div id="root_panelext-14-bounding-box" class="widget-bounding-box nonresponsive" style="top: 5px; left: 5px; width: 337px; height: 218px; z-index: 1510;">
    <div class="widget-content widget-panelext card text-white bg-secondary" id="root_panelext-14" style="width: 337px; height: 218px;">
        <div class="card-header"> Caption Test </div>
        <div class="card-body" sub-widget-container-id="panelext-14" sub-widget="1">
            <h5 class="card-title">Card Title</h5>
            <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card content.</p>
        </div>
        <div id="root_flexcontainer-15-bounding-box" class="widget-bounding-box nonresponsive widget-flexcontainer-bounding-box no-flex-wrap flex-leaf-static" style="position: relative; z-index: 1510; flex: 1 1 auto;">
            <div class="widget-content widget-flexcontainer widget-container tw-flex-row"
                style="background: -webkit-linear-gradient(top, rgb(0, 96, 204) 0%, rgb(1, 61, 182) 100%); border-width: 1px; border-color: rgb(1, 52, 154); border-style: solid; flex-flow: row nowrap; align-items: flex-start; place-content: flex-start;"
                id="root_flexcontainer-15"></div>
        </div>
    </div>
</div>

So the bounding-box of the flexcontainer in added after the body-tag, not inside.

How can I tell a dynamic created widget which <div> to use?

 

Greetings

 

Andreas

    @atondorf ,

     

    Cool widget idea!  

     

    One thought, could you utilize the afterRender() function and jQuery to switch the parent element of that <div>? 

     

    Similar to the one of the suggestions on this post: https://stackoverflow.com/questions/2596833/how-to-move-child-element-from-one-parent-to-another-using-jquery

    Hi @nmilleson 

     

    thanks for the tip, but this is exactly what thingworx mashups system should do automatically and in fact it can!

    I searched the complete mashup kernel and finally found the answer in the function

    "TW.Widget.appendWidgetChildren":
    This is the code that attaches SubWidgets to the Elements in the Container,
    • The code first checks the parent widget for the runtime property "isContainerWithDeclarativeSpotsForSubWidgets".
      • If propetry is false, it attaches the Widget to the contentElement (class="widget-content") 
      • If propery is true, it searches for child elements with sub-widget-container-id="[widget-Id]" sub-widget="[Nr of Subwidget]", and attaches it ... 

    So the central code of my widget now looks like:

     

    this.widgetProperties = function () {
        let properties = {};
        let result = {
            name: "bsCard",
            category: ['Common', 'Containers'],
            isContainer: true,
            isDraggable: true,
            supportsAutoResize: true,
            isContainerWithDeclarativeSpotsForSubWidgets: true,
            properties: properties,
        };
        return result;
    };

    this.afterCreate = function() {
     thisWidget.addWidget(this._createContainer(0), true);
    };

    this.renderHtml = function () {
        var html = "";
        html += '<div class="widget-content widget-bsCard card text-white bg-secondary">';
        html += '<div class="card-header"> Header Test </div>';        
        html += '<div class="card-body" sub-widget-container-id="' + this.properties.Id + '" sub-widget="1">';
        html += '</div></div>';
        return html;
    };

    this._createContainer = function (tabNo) {
     var containerType = TW.IDE.isFlexLayout ? 'flexcontainer' : 'container';
     var containerDisplayName = (TW.IDE.isFlexLayout ? 'Responsive Tab' : 'Tab') + ' #' + (tabNo + 1);
     var widgetToAdd = TW.IDE.Widget.factory({ Type: containerType });
     var newId = TW.IDE.Workspace.Mashups.NewID(containerType);
     widgetToAdd.setProperty('Id', newId);
     widgetToAdd.setInternalProperty('DisplayName', containerDisplayName);
     widgetToAdd.setInternalProperty('ResponsiveLayout', true);
     widgetToAdd.setProperty('userCannotRemove', true);
     return widgetToAdd;
    };

    Also very important, as the runtimeProperties from IDE code are not forwarded to the runtime code:

    TW.Runtime.Widgets.bsCard= function () {
        this.runtimeProperties = function () {
            return {
                isContainerWithDeclarativeSpotsForSubWidgets: true
            };
        };
        this.renderHtml = function () {
            var html = "";
            html += '<div class="widget-content widget-bsCard card text-white bg-secondary">';
            html += '<div class="card-header"> Header Test </div>';        
            html += '<div class="card-body" sub-widget-container-id="' + this.properties.Id + '" sub-widget="1">';
            html += '</div></div>';
            return html;
        };
    };
    The result is looking quite nice:
    bootstrap-Card-widget.png
    The green box is the dynamicly created flexcontainer and all flexcontainer functions seem to work inside the MashupBuilder (eg. Wrap of Items, dividing by row&column, etc.). But currently the flexcontainer is only working well in the IDE, especially the size. In runtime the margins look little different and it does not automatically scale to the size of the card body Element. So still some work to do ... 
     
    So any idea & tips still welcome!
