DecSoft App Builder

Html description

The Html control is one of the most powerful controls that we can use in our apps. This is because this control allows to use freely HTML markup to be show. Even more, we can use the VueJS library template syntax inside the markup HTML.

We can place almost any piece of HTML markup that uses the Boostrap CSS framework (any of their components, for example) and we can get it working probably without changes. And we can use the VueJS template syntax to parse and show any kind of app variable.

See the control Html property for more details.

There is a Html sample app included with the installation of DecSoft App Builder. Take a look to see this control in action!

Html CSS rules

This control has a default style, and, some control JavaScript properties (see below), can also changes the control style, not to mention the Classes property, that you can use to establish one or more CSS classes to be applied to the control.

In addition to that style, you can also set custom CSS rules for the control by using the IDE controls style inspector. If this is not enough, you can include any number of CSS stylesheets in the app by using the app files manager.

If you want to use CSS stylesheets, you need to know how to refer to the control, so take a look at the Runtime selectors help topic.

Html at designtime

The Html control put at your disposition the below designtime properties or variables. Designtime means here that these properties are only available in designtime and not in runtime.

Html at runtime

The Html control put at your disposition the below runtime properties or variables. You can set almost all these variables in designtime, and, they are also available to be use when the app is running. Note that we named here these variables in a capitalized way, because is like you can see it in the designtime control's inspector, however, at runtime we use the lower camel case way.

Html events

The Html control put at your disposition the below events handlers:

Html designtime properties

Html Top property

Designtime. Integer variable. The Top property stores the top position of the control in pixels. The pixels are relative to the app view, dialog or frame, and, is used "as is" if the app have the "Scale" app option is set to "false". Remember that this control property is only for designtime and is not available in runtime.

Html Left property

Designtime. Integer variable. The Left property stores the left position of the control in pixels. The pixels are relative to the app view, dialog or frame, and, is used "as is" if the app have the "Scale" app option is set to "false". Remember that this control property is only for designtime and is not available in runtime.

Html Width property

Designtime. Integer variable. The Width property stores the width of the control in pixels. The pixels are relative to the app view, dialog or frame, and, is used "as is" if the app have the "Scale" app option is set to "false". Remember that this control property is only for designtime and is not available in runtime.

Html Height property

Designtime. Integer variable. The Height property stores the height of the control in pixels. The pixels are relative to the app view, dialog or frame, and, is used "as is" if the app have the "Scale" app option is set to "false". Remember that this control property is only for designtime and is not available in runtime.

Html Locked property

Designtime. Boolean variable. The Locked property determines if the control can be moved or resized in app view designer or not. Set a "false" value mean the control can be moved and resized. Set a "true" value (by default) mean the control cannot be moved nor resized. Remember that this control property is only for designtime and is not available in runtime.

Html runtime properties

Html Name property

Runtime. String variable. The Name control property stores the name of the Html control as you set in designtime. The Name property value must be unique for the same app view, dialog or frame, that is, it's possible to have more than one "html1" in the app, if that controls resides in different app views, dialogs or frames. Note that you must consider this variable as read only: change the name of a control in runtime can cause unexpected results.

Html Event property

Runtime. Mixed variable. The Event control property stores the "event" variable received in all the control events. This variable can contain the target (HTML element of the control) that fire the event and more useful stuff.

Html Html property

Runtime. String variable. The Html control property stores HTML markup that must be show in the app view, app dialog or app frame. In the control description has been mentioned that this the HTML control is one of the most powerful in DecSoft App Builder, and, the Html property of this control is the key.

The Html control property can store almost any HTML markup, and, specifically, we can prepare the HTML markup using the power of the available Boostrap CSS framework. Additionally, and, since the VueJS library is also available to use, we can use all the power of the VueJS template syntax, for example, to show any kind of app variable in the right way.

Here is a sample of use of the Html property to propertly show certain app variable:

Then the control Html property can look like below:

Doing that you get a cute Bootstrap CSS list filled with the "userList" app variable.

You can directly paste the HTML that exists in your clipboard into the app view, app dialog or app frame designers, so a new HTML control is automatically created with the clipboard HTML in their Html property.

Html Title property

Runtime. String variable. The Title control property stores some small but descriptive text, mainly to be used to be show that text when the user place the mouse cursor into the control.

Html Classes property

Runtime. String variable. The Classes control property stores one or more additionals CSS classes (space separated) to be applied to the control.

Html Hidden property

Runtime. Boolean variable. The Hidden control property determines if the control appear visible to the user or not. Set to "true" to hide the control, or to "false" to show the control (by default).
