Hi , about webView2Demo,
I want to integrate webView2Demo into my project, but the dificulty is the following:
this command in main.pro does not work in Taskwindow? (question). Also, the navigation result is not the same with or without this comand especially for the quotes graphic in internet.
Code: Select all
clauses
run() :-
if webView2_api::ensureWebView2() then
webView2::setDefaultEnvironment({ (C) :-
webView2_api::createCoreWebView2Environment(C, @"..\webView2UserData") }),
_ = mainForm::display(gui::getScreenWindow()),
messageLoop::run()
end if.
thank you for your contribution
regards
Gass

In an SDI application (with a
mainForm) the "main" code looks like this:
Code: Select all
clauses
run() :-
_ = mainForm::display(gui::getScreenWindow()),
messageLoop::run().
In an MDI application (with a
taskWindow) then main code looks like this:
Code: Select all
clauses
run() :-
TaskWindow = taskWindow::new(),
TaskWindow:show().
So a possibility could be:
Code: Select all
clauses
run() :-
if webView2_api::ensureWebView2() then
webView2::setDefaultEnvironment(
{ (C) :-
webView2_api::createCoreWebView2Environment(C, @"..\webView2UserData")
}),
TaskWindow = taskWindow::new(),
TaskWindow:show()
end if.

Hi Thomas,
Ok with the last command run(), but how to call the class web.frm (web) from Taskwindow, because it appears but nothing concerning Webview2.
thanks again,
regards

Hi Thomas,
I'm looking for ribbonMdiDemo to maybe find the solution to my problem: launch a program with de web open and navigate.

I am not sure if I understand the problem, but maybe this will help.
To show your
web form (from your
taskWindow), you will have to make a call like this:
In the default code a
messageForm is displayed in the show-listener, and the
aboutdialog is displayed in a menu handler.
You can add additional arguments to
web::display (e.g. the URL to navigate to) or you can add additional predicates to its interface. For example you can "export"
navigate like this:
Code: Select all
interface web supports formWindow
predicates from iWebView2
navigate
...
And implement it using
delegation:
Code: Select all
implement web inherits fromWindow
...
delegate
navigate to webView2_ctl
Given that you can start and navigate like this:
Code: Select all
WebForm = web::display(This),
WebForm:navigate(Url)
