Bug 77096 – Web Inspector: [Meta] Allow emulation of touch events

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Alexander Pavlov (apavlov)]

Web developers writing for mobile devices will want to debug touch events on their desktop hardware lacking touch screens. We need to enable the emulation of touch events using the similar, mouse-related ones (like, mousedown -> touchstart).

What about the documents that are added / removed from the list dynamically? You should also adjust their settings.

I don't think you need this change.

This should not be under the showDockToRight.

You should do this via the page agent.

> Source/WebCore/inspector/InspectorDOMAgent.cpp:1069
> +    m_state->setBoolean(DOMAgentState::touchEventEmulationEnabled, enabled);

You should move this into the updateTouchEventEmulationInPage.

I think we should rename "Network" to "User Agent", move Disable cache into "General"

I thought backend was ready for the emulation. Please fix this separately as a follow up to the backend change.

You should hide this.

> +    if (m_state->getBoolean(DOMAgentState::touchEventEmulationEnabled) == enabled)

You could put this above the ENABLE as an entry guard.

> Source/WebCore/inspector/InspectorDOMAgent.cpp:1072
> +    *error = "Touch event emulation not enabled";

Touch events emulation not supported.

> Source/WebCore/inspector/front-end/SettingsScreen.js:43
> +    if (Preferences.showDockToRight && Preferences.exposeDisableCache) {

&& -> ||

> Source/WebCore/page/EventHandler.cpp:1783
> +#if ENABLE(TOUCH_EVENTS)

Should be in a separate change.
