Working with Ext JS: Dynamically adjusting panel size when the browser window is resized

I am facing an issue with a side panel in Ext.js. Everything is working fine until I resize the browser, at which point some components of the panel get cut off.

Is there a way to make the panel resize automatically when the browser is resized?

{
        xtype: 'panel',
        border: 1,
        margin: 5,
        flex: 1,
        autoScroll: true,
        layout: {
            type: 'vbox',
            align: 'stretch'
        },
        items: [
            {
                xtype: 'panel',
                title: localization.moduleS.labelOutlineAttributesField,
                border: 0,
                bodyPadding: '12 5 12 5',
                className: 'outlineAttrField',
                hidden: true,
                items: [
                ]
            },
            {
                xtype: 'sattrfillinpanel',
                title: localization.moduleS.labelFillInAttributesField,
                border: 0,

                hidden: true
            },

                        border: 0,
                        margin: '0, 5, 0, 2',

                                label: localization.moduleS.labelShowAttributesOnLeftField
                            },
                            {
                                xtype: 'sfeaturefilterpanel',
                                margin: '0 0 0 0',

                                label: localization.moduleS.labelShowAttributesOnRightField
                            }
                        ]
                    },
                ]
            },

The filters field is experiencing the cutting off issue.

Answer №1

The issue doesn't seem to lie with your panel resizing but rather with the components inside it. I believe your code is correct, but the problem may be within the internal components of the panel.

Personally, when using a vbox or hbox layout within a panel, I always assign a flex value to the components inside. This ensures that they resize properly during browser events without needing manual adjustments.

I recommend trying to apply a flex value to your components and see if that resolves the resizing issue.

In the past, I found examples of layouts particularly helpful in understanding how to use them effectively. Here's a link to some examples:

By utilizing a viewport with a panel inside and a vbox layout with specified flex values, I consistently achieved the desired resizing behavior.

Sometimes, especially after making significant changes, it may be necessary to refresh the layout of your components manually.
