I recently purchased Trichview.
For 2 weeks, I could not till now view a docx file stored in Application folder in my android device.
I need a simple and example code of how to do that.

If DocX file (let its name is 'example.docx') is deployed to
assets\internal, you can load it as:
Code: Select all
uses System.IOUtils;
var
FileName: String;
begin
FileName := IncludeTrailingPathDelimiter(System.IOUtils.TPath.GetDocumentsPath) + 'example.docx';
RichViewEdit1.Clear;
RichViewEdit1.LoadDocX(FileName);
RichViewEdit1.Format;
end;
This example assumes that you placed RichViewEdit1: TRichViewEdit and RVStyle1: TRVStyle on the form, and assigned RichViewEdit1.Style = RVStyle1.

Also, you can check demo projects in <TRichView Dir>\Demos\Delphi.FMX\ folder.
For example, "Editors\Editor 2\" demo.
Editor demos allow opening files (including DocX files) from common location of Android device.
The procedure is slightly more difficult than opening application-local files: a file choosing dialog returns not a file name, but file URL.
Details of file choosing on Android and iOS are described here:

"Unicode" property of text styles is an obsolete property, it does nothing, all text is always Unicode.
1) Probably, to display your file properly, you should define the main text direction in the document.
Assign RichViewEdit1.BiDiMode = rvbdRightToLeft to set RTL direction, or rvbdLeftToRight to set LTR direction.
Do it before loading DocX. Some bi-di properties are not loaded from DocX is BiDiMode = rvbdUnspecified.
2) To make sure that all DocX properties are loaded. Right click RichViewEdit1 at design time, choose "Settings" in the popup menu.
To load all DocX text and paragraph properties, the setting on the first page must be "Allow adding styles dynamically" or "Allow adding styles dynamically + StyleTemplates".
