Impressive. Wow.

[Rollo62 536]

This is pretty much overwhelming.

I'm afraid there is already a point here where users are shocked by the functionality and need a gentle way to climb the learning curve.

In my opinion, it is always best to have many examples covering different levels of difficulty to understand the whole concept behind it piece-by-piece.
If there is a clear usage concept behind it, how could you explain it in the docs, maybe step by step?

Maybe a user needs a mix of Delphi and HTML/JS knowledge to understand most of it, how can these lessons be broken down into small, digestible chunks?

You can get first working application with almost zero coding. Simply load demo project, enter your database credentials (or leave sample database) and press button to generate UI. Application is ready.

Now start browser, switch do design mode (F2) and use designers to adjust tables, tabs, etc as shown in video. Each designer has help ? button in caption which leads to manual.

 

Typical workflow is described there https://delphihtmlcomponents.com/webui/typical-workflow.html

1. Build UI with default settings.
2. Check created UI and make TWebUIBuilder descendant with overridden rules.
3. Create UI using your TWebUIBuilder descendant and analyze it.
4. Repeat steps 2, 3 until you get an acceptable result.
5. Use WebUI designers for final polishing.

Also there are Server and UI sections which itself are samples, you can open any table or action (button) designer and see how it works.
More samples and tutorials will definitely be added later.

Is WebUI optimized for mobile devices, or just for devices with large screens (computers)?

Currently there is only desktop layout, but since UI is stored in an intermediate representation, there will be no need for modifications when mobile templates will be added.

[Alexander Sviridenkov 356]

Demo is updated with Postgres client libraries and better error handling.

[Alexander Sviridenkov 356]

Document Viewer is added to Demo (Word, Excel, PDF, Powerpoint, etc.).

1. Create UI and start Server

2. Open Documens section

3. Press F2 to switch to design mode

4. Using gear icon above documents table and at view window (right) open designers and change documents folder/mask.

Hi Alexander,

 

do you have a sample for THtListView?
