Weather

In the library, we provide you with a wealth of widgets, and in order to reduce the design complexity of your project production process, we preset some styles for these widgets, but we can still modify their styles on this basis.

1. Add widgets

If you are not familiar with widgets, you can find the widget in the widget window and add it:

If you are familiar with widgets, you can add widgets by searching, which is more convenient.

Click the search button or press “Ctrl+F” to open the search box, enter the widget name to search, and then click the corresponding widget to add it.

2. Select a city

You can enter the city weather you want to display in “City”. Currently, only the weather of cities in China is supported.

3. Set widget Style

Click to select the widget. In the “Style” settings window on the right, you will see various categories of settings. Each category contains different options, and these categories and options will vary depending on the widget.

3.1 Fixed style settings

Fixed style is the widget style that remains unchanged after setting. This corresponds to the conditional style in Chapter 3.2. The conditional style changes the widget style according to the change of data.

Below we will introduce the specific settings for each setting item.

3.1.1 Basic Settings

The opacity of the Weather widget changes, as shown in the following figure:

3.1.2 Icon Settings

Weather widget icon style settings, as shown below:

3.1.3 Weather Name

Only when you turn on the weather component, the corresponding city weather text will be displayed, and the text settings will be synchronized to the date font.

Weather widget text settings, as shown below:

3.1.4 Show Temperature

Only when you turn on the button will the weather component display the temperature of the corresponding city.

Weather widget temperature settings, as shown below:

3.1.5 Size & Position

You can adjust the size and position of the widget by directly clicking and dragging it, or by entering the width, height, X coordinate, and Y coordinate values directly.

Size & Position Parameters for Weather widget, as shown in the figure below:

3.1.6 Border Settings

The border style will only be displayed and configurable for the widget once the **”Border Settings” **option is enabled.

The border style of Weather is as shown below:

3.1.7 Background Settings

By default, widgets have no background color. To set a background color, you first need to enable the “Background Settings” option.

Tile fill background color, as shown below:

3.2 Conditional style settings

Conditional styles are styles that widgets change according to data conditions.

Almost all setting items can be set with conditional styles, but different setting items have slightly different conditions when setting conditional styles. There are two specific ways:

Method 1: Set in the extended settings menu

The conditional setting method for most setting items is method 1. The specific steps are as follows:

Take the “Opacity” setting item in “Basic Settings” as an example:

Click to select the component and move the mouse over the setting item. You will see three dots (extended setting button) appear on the right side of the setting item name.

Click these three dots to open the extended settings window, and the first option is “Conditional Style”.

Click “Conditional Style” to open the conditional style settings window.

Click “+ Add conditional style” and select the data condition to be triggered (the optional data condition here must be an existing data condition).

According to the current settings, we can set the opacity value when condition 1 is met, and the opacity value when none of the conditions are met.

After the settings are completed, a prompt “Conditional style enabled” will appear in the setting item.

Method 2: Set directly in the setting item

Some setting items have conditional settings that are directly displayed in the setting item. In this case, you can set them directly outside. However, the conditional style of multi-line text can only be set through method 1.

3.3 Set styles by data fields

The essence of all setting item modifications is to modify the values, so all setting items can be controlled through data fields, and the dynamic data field function is required here.

Still taking the “Opacity” setting in “Basic Settings” as an example:

Open the extended settings window and click the option “Generate Field”.

After clicking, a prompt “Please set data fields” will appear in the setting item.

Switch to the “Data” setting interface. You can see that a new “Dynamic Data Fields” setting item has been added to the interface, and an associated field has been generated for the “Opacity” setting item just selected.

Next, you just need to add a data field here, and you can control the opacity through data.

Add a data with a value of “0” to the data field, and you can see that the opacity value is changed to “0” through the dynamic data field, making the component hidden.

4. Set interaction

Click to select a widget, and in the “Interact” setting window on the right, you can add or delete interactions for the current widget.

5. Secondary Development

Click on the widget to select it, and in the right-side “Code” settings window, you can configure secondary development settings for the widget.

Secondary development needs to be achieved by loading JavaScript script files.

Click “+” to add settings. Multiple scripts can add multiple settings.

During the secondary development process, we can control the style of the widget. If we want to control a certain setting item, we can first view the secondary development code example of the setting item in the style.

Take the “Opacity” setting item as an example:

Open the pop-up window of the extended settings and click “Sample code”.

You can see the secondary development code sample for this setting item.

Here is a simple secondary development example:

Secondary development function: widgets automatically move to the right

 * Extension.prototype.enabled;
 * Extension.findExtensionsOfClass(className)
 * Element.prototype.setOption()
 * Element.prototype.getOption()
 * Element.prototype.getFullData()
 * Element.prototype.name
 */
class Button {
  update() {
    const position = this.element.getOption(["position"]);
    // The current element moves a certain distance on the X axis
    this.element.setOption(
      ["position"],
      [(position[0] + 1) % 100, position[1]]
    );
  }
}
export default Button;

Click “Select File” to add the JavaScript file.

6. Set up multi-state switching

6.1 Add states

Each widget has a default state property, which contains all the above settings.

But we can also add multiple states, so that each state will contain all the above settings, and these states are independent of each other.

We can add new states in the following two ways:

(1) Create a new state

Click the “+” in the upper right corner to add a new widget state.

In the state setting window, we can set the name of the state.

By default, all new states are kept consistent with the default state.

We also open the advanced settings in the window to set the follow object of the new state.

(2) Copy an existing state

Click the state name in the upper right corner to expand the state list. After expanding, you can see all the states of the current widget.

In this state list, we can rename, copy and delete the state.

Click the copy button on the right side of the state name to copy the current state to a new state. All settings of the copied new state will be consistent with the copied object state.

6.2 Switch states

When editing a project, we can manually switch widget states by clicking on different states in the state list.

Switching widget states through click interactions usually involves clicking other widgets to switch the state of the current widget, so the interaction is set on other widgets rather than on the current widget. For example, clicking a button switches the display and hide states of the current widget.

First, set a hidden state for the widget (the default state is considered as the visible state).

Click “+” to create a new “Hidden” state, and then change the widget opacity to “0%” in this state.

Add a “Show” button and a “Hide” button.

Add an interaction to the “Show” button , and switch the widget to the default state (show state) after clicking.

Add an interaction to the “Hide” button to switch the widget to the hidden state after clicking.

This achieves the effect of switching the display/hide of components by clicking the button.

6.3 Locked state

In the style settings, some settings have a lock icon on them, which means that this setting item in all current states has been locked to the default state, which means that if this setting item is modified, this setting item in all states will be modified uniformly.

This is a function that allows you to uniformly modify the same setting items in multiple states in a widget’s multiple states.

If you don’t want to lock it, you can click to unlock it, and then this setting item in all states will be unlocked.

If you want to lock other settings, you can click the three dots on the right side of the setting item and then lock it.
