An argument is that it is not 100% sure that we're going to connect to this "recommended" gateway. However, it's fair to tell the user what's likely to be the recomended location, to make a better choice. ALso, we can implement a warning if finally connecting to a different location. That said, all is made worse by the fact that menshen will not return the "right" location if we're connecting from the vpn, a proxy etc... For that we need to modify menshen to accept a location parameter. Disabling the hint for now, but some agreement needs to be done on android + desktop about this behavior. if (ctx && ctx.locations && ctx.bestLocation) { let best = ctx.locationLabels[ctx.bestLocation] let label = best[0] + ", " + best[1] l += " (" + label + ")" } */ return l } function getLocationLabel(location) { if (!ctx) { return "" } let l = ctx.locationLabels[location] return l[0] + ", " + l[1] } function getManualBoxHeight() { let h = Math.min( root.locationsModel.length * 35, root.appHeight - autoBox.height - 100 ) if (bridgeWarning.visible) { h += bridgeWarning.height } return h + 50 } function getSignalFor(location) { // this is an ad-hoc solution for the no-menshen, riseup case. // when menshen is deployed we'll want to tweak the values for each bucket. let load = ctx.locations[location] switch (true) { case (load > 0.5): return "good" case (load > 0.25): return "medium" default: return "low" } } function getLocationColor() { if (ctx && ctx.status == "on") { return "black" } else { // TODO darker gray return "gray" } } function isBridgeSelected() { if (ctx && ctx.transport == "obfs4") { return true } else { return false } } function getManualAnchor() { if (isBridgeSelected()) { return bridgeWarning.bottom } else { return manualLabel.bottom } } Component.onCompleted: { if (root.selectedGateway == "auto") { autoRadioButton.checked = true } else { let match = false for (var i = 1; i < locsel.buttons.length; i++) { let b = locsel.buttons[i] if (b.location == root.selectedGateway) { match = true b.checked = true } } } } }
