文章数量:1277322

I am working on an Electron app and as part of the interface I want to increase the size of the window once something has happened (I have bound this to a button for now) so I can display additional data. I have attempted to do this with the following code that is activated on a onclick=resize():

require('./renderer.js');

let remote = require('electron').remote;
function resize() {
    let win = remote.getCurrentWindow().setBounds({
        height: 1000
    });
}

However, I am getting the following error in the window/browser console:

Uncaught Error: Could not call remote function 'setBounds'. Check that the function signature is correct. Underlying error: Error processing argument at index 0, conversion failure from #<Object>

• 1 Have you tried providing every props for rectangular object? Docs doesn't mark any prop as optional. And have you tried setSize(w, h)? – pergy Commented Dec 4, 2017 at 5:30
• @pergy that worked, thanks. Would you like to post it as an answer so I can give you the rep, etc. – Thomas Smyth Commented Dec 4, 2017 at 10:56

Sorted by: Reset to default 6

Definition of Rectangle object (which is the first argument of setBounds) is more strict than you expected. Since its properties don't have default values you have to define all of them.

For example:

remote.getCurrentWindow().setBounds({
    x: 1621,
    y: 611,
    width: 10,
    height: 1000
});

Also, if you want to adjust only size you can use setSize of BrowserWindow

Just use plain old javascript from the renderer, I would not add an unnecessary messaging between main and renderer process if it is just a resize ;)

window.resizeTo(1000,900);

If anyone's getting a similar error, make sure you provide integer values, for example 123, not 123,45. Math.round them to make sure.

I don't see a mention of this in the documentation sadly.
