[resolved]Open file dialog in webView
-
Hi, i have a project with a webview (i use qml). The navigation works fine but i now i would like to open a FileDialog to upload a file. I need this because my application need to upload parameters to a device with a html page. See the picture under :
The problem is that when i click "choose file", nothing happen ... What i need is to open a filedialog, select a file and upload it to my device...
My simple code (get from an exemple) :
ScrollView { Layout.preferredWidth: (tabView.width)-30 Layout.preferredHeight: 500 WebView { id: webview url: "http://192.168.1.121" anchors.fill: parent onNavigationRequested: { // detect URL scheme prefix, most likely an external link var schemaRE = /^\w+:/; if (schemaRE.test(request.url)) { request.action = WebView.AcceptRequest; } else { request.action = WebView.IgnoreRequest; // delegate request.url here } } } }Can you give me some help ?

@modjo756 Have a look at WebChannel.

@modjo756 Also for file choose what html type have you used ? input type as
fileworks. IT opens file choose dialog. Here's the HTML:<!DOCTYPE html> <html> <body> <input name="File" id="file" type="file"> </body> </html>See if it invokes the file dialog on your system.

I didn't realize the HTML page. The device (that we have bought) is connected to the network by ethernet. To update (or load) parameters we can do this by a browser like chrome -> this works. Now i have my app (realized with qt5.5 qml/c++) and i would like to update the parameter from it, that's the reason i use a webview. Do you understand what i want ?
