Handling HTML text in an Edit control
HyperText Markup Language (HTML) is a markup language intended for the web. WEBDEV allows you to handle text in HTML via the "HTML format" option of the Edit controls and the HTML control. - If the HTML text is displayed in a control that does not support HTML, the tags will be displayed.
- If the HTML text is displayed in a control that supports HTML, the tags will be automatically interpreted and the text will be formatted accordingly.
Overview The HTML Edit control is used to: - display HTML content,
- enter HTML content.
The control automatically stores entered text as HTML. This text will contain all the necessary formatting tags. Control characteristics The HTML Edit control has several options ("General" tab in the description window): - HTML toolbar: A formatting toolbar can be displayed above the Edit control. This toolbar allows the user to easily format the text entered. For more details, see HTML formatting toolbar.
- Action on Enter key: Defines what the Enter key does in the HTML Edit control.
 New in version 28Email editing: Enables an "email" input mode that limits the HTML functionalities to those recognized by most email clients. New in version 28Content independent of page style: Applies the style only to the the input field. No other style will be applied to the text in the input field.
Remark: A given string will be longer in an HTML Edit control than in a standard Edit control, because HTML tags are added. WLanguage events associated with the control New in version 28The optional "Key pushed" event, available in browser code, allows you to create shortcuts using F keys, etc. Defining the content of an HTML Edit control To define the content of an HTML Edit control, simply specify the Value property (in the initialization code of the control, for example). For example: // Read an HTML file
HTMLPage is string
HTMLPage = fLoadText(SysDir(srMyDocuments) + ["\"] + "index.html")
// Initialize the edit control
EDT_HTMLControl = HTMLPage Saving a text in an HTML file HTML formatting is automatically applied to the text entered in an HTML Edit control. To save the content of an HTML Edit control to an HTML file, simply use fSaveText on the control. Example The example below creates an "index.html" file. This file contains the text entered in EDT_HTMLText. // Select the path and name of the file
FileName is string
FileName = fSelect("", "", "Select a file...", ...
"HTML files" + TAB + "*.html" + CR + "All files (*.*)" + TAB + "*.*", ...
"HTML", fselCreate + fselExist)
// Backup
fSaveText(FileName, EDT_HTMLText) Saving HTML text to an HFSQL data file item To save HTML text to an item of a data file, it is recommended to bind the Edit control to a Text Memo item. As HTML includes many tags, "Character string" items are often too small. |
