Query on MMM-CalendarExt3 modification

[sdetweil]

@sharkbait I use MMM-pages to do that with 3 instances of MMM-CalendarExt3 (this month, next(jan) and next (feb) (auto rolling to current/next/next+1)
(you would use monthIndex -1, 0, 1)
i also use MMM-PageIndicator which provides buttons… and you can click to move to diferent pages

those module configs

 {
        module: "MMM-CalendarExt3",
        position: "middle_center",
        classes: "page1",

calendar config minus urls

      {

          getRelative: 0,
          calendars:[
         ]
     }
}

no modules are modified

to enable cursor on MM in custom.css do

html {
 cursor: default;
}

to override the cursor:none; in main.css

[sdetweil]

@sharkbait
and you can change the pageindicator circles to full button icons thru css

MagicMirror is an open-source project with a modular structure. Modifying the original modules can make updates difficult, so it’s best to avoid it when possible. Fortunately, in CX3, you can easily implement the desired functionality by creating and adding a simple custom module without directly modifying the source code.

To dynamically change CX3’s view at runtime, you can use the method suggested by sdetweil, which involves creating multiple instances and switching them out one by one. However, this can also be implemented more simply using only notifications.

The example module below demonstrates how to add two simple buttons to the screen. This module utilizes MagicMirror’s notification architecture to transform CX3’s view when the button is clicked.

MMM-ButtonExample

/* modules/MMM-ButtonExample/MMM-ButtonExample.js */
Module.register("MMM-ButtonExample", {
  getDom: function () {
    const wrapper = document.createElement("div")
    const button1 = document.createElement("button")
    button1.innerHTML = "Current Month"
    button1.onclick = () => {
      this.sendNotification("CX3_RESET", {
        callback: (currentConfig) => {
          console.log("Return to the original config")
        }
      })
    }
    const button2 = document.createElement("button")
    button2.innerHTML = "Next Month"
    button2.onclick = () => {
      this.sendNotification("CX3_GET_CONFIG", {
        callback: (currentConfig) => {
          this.sendNotification("CX3_SET_CONFIG", {
            monthIndex: currentConfig.monthIndex + 1
          })
        }
      })
    }
    wrapper.appendChild(button1)
    wrapper.appendChild(button2)
    return wrapper
  }
})

/* config/config.js */
...
{
	module: "MMM-CalendarExt3",
	position: "bottom_bar",
	config: {
		mode: 'month',
	}
},
{
	module: "MMM-ButtonExample",
	position: "bottom_bar",
},
...

More polished version.

MMM-CustomInjection

/* modules/MMM-CustomInjection/MMM-CustomInjection.js */
Module.register("MMM-CustomInjection", {
  getStyles: function () {
    return [
      this.file("MMM-CustomInjection.css")
    ]
  },

  notificationReceived: function (notification, payload, sender) {
    if (notification === "CX3_DOM_UPDATED") {
      const { instanceId } = payload
      this.inject(instanceId)
    }
  },

  inject: function (instanceId) {
    const moduleDom = document.querySelector(`#${instanceId}`)
    if (!moduleDom) return
    moduleDom.classList.add('custom-injected')
    const buttons = document.createElement('div')
    buttons.className = 'calendar-header-buttons'
    const prev = document.createElement('button')
    prev.className = 'calendar-header-button'
    prev.innerHTML = 'PREV'
    prev.onclick = () => {
      this.sendNotification('CX3_GET_CONFIG', {
        callback: (currentConfig) => {
          this.sendNotification('CX3_SET_CONFIG', {
            monthIndex: currentConfig.monthIndex - 1,
          })
        }
      })
    }
    const current = document.createElement('button')
    current.className = 'calendar-header-button'
    current.innerHTML = 'CURRENT'
    current.onclick = () => {
      this.sendNotification('CX3_RESET', {})
    }
    const next = document.createElement('button')
    next.className = 'calendar-header-button'
    next.innerHTML = 'NEXT'
    next.onclick = () => {
      this.sendNotification('CX3_GET_CONFIG', {
        callback: (currentConfig) => {
          this.sendNotification('CX3_SET_CONFIG', {
            monthIndex: currentConfig.monthIndex + 1,
          })
        }
      })
    }
    buttons.appendChild(prev)
    buttons.appendChild(current)
    buttons.appendChild(next)
    moduleDom.appendChild(buttons)
  }
})

/* modules/MMM-CustomInjection/MMM-CustomInjection.css */
.custom-injected {
  position: relative;

  .calendar-header-buttons {
    position: absolute;
    top: 30px;
    right: 0;
    display: flex;
    flex-direction: row;
    justify-content: space-between;
    gap: 10px;
    width: fit-content;

    .calendar-header-button {
      background-color: transparent;
      border: none;
      color: white;
      font-weight: bold;
    }
  }
}

@sdetweil Thank you for taking the time to read my post and providing the guidance, and the additional modules I could try out. I have tried the 2 extensions as per your recommendation. The transition between pages is slick when set to auto rotate but for some reason, the page indicator module doesn’t allow me to switch (tap) between pages manually on my touchscreen, when I disable the auto-rotate .

[sharkbait]

@MMRIZE Thank you for the taking the effort to provide me with the set of code. I’ve tested it and it works wonderfully.

[sharkbait]

@MMRIZE I tried to implement this CustomInjection code but the rendered display turned out like this ![alt text]https://drive.google.com/file/d/1OUJ3EBz1CNMVqA9ds7kQhc4sTuovUoUA/view?usp=sharing.

My setting in config.js is as follows:
…,
{
module: “MMM-CustomInjection”,
position: “bottom_bar”,
},

Instead of buttons, what I see is just the module name (MMM-CustomInjection, and below that module_5_MMM-CustomInjection).

This is definitely a more polished solution, but I’m not sure why the display could not be rendered.

[sdetweil]

@sharkbait
and you set

      rotationTime: 0, 

correct??

it works for me…

and u did change the cursor setting in css… right?

[MMRIZE]

@sharkbait
MMM-CustomInjection doesn’t need to be positioned because that module works on background.

/* config/config.js */
{
	module: "MMM-CalendarExt3",
	position: "bottom_bar",
	config: {
		mode: 'month',
	}
},
{
	module: "MMM-CustomInjection",
},

[sharkbait]

@sdetweil I added this entry to custom.css:

html {
  cursor: default;
}

For config.js, my settings for “MMM-CalendarExt3”, “MMM-pages” and “MMM-page-indicator” were as follows:

	{
		  module: "MMM-CalendarExt3",
		  position: "bottom_bar",
		  classes:"page3",
		  title: "Our Family Calendar",
		  config: {
			mode: "month",
			headerWeekDayOptions: {
				weekday: "narrow"
			},
			cellDateOptions: { day: 'numeric' }, // suppress month from appear in cellDate
			monthIndex: 0, //0=curr_month, -1=prev, 1=next
			maxEventLines: {0:6, 6:5}, 
			firstDayOfWeek: 0,
			calendarSet: [],
			fontSize: '18px',
			refreshInterval: 120000,
		  },
		  disabled: false,
	},

		  {
			module: "MMM-page-indicator",
			position: "bottom_bar",
			order: "*",
			config: {},
			disabled: false,
			classes: "fixed"
		  },
	// pages
		  {
			module: "MMM-pages",
			disabled: false,
			config: {
			  modules: [
				[
				  "page1"
				],
				[
				  "page2"
				],
				[
				  "page3"
				]
			  ],
			  fixed: [
				"fixed"
			  ],
			  animationTime: 10000, // time of fade in/out on page change
			  rotationTime: 0,  // if you make this 0, then the pages only turn manually or via notification from somewhere else (indicator)
			  hiddenPages: {
			  }
			},
			order: "*"
		  },

A white circular dot at the bottom indicates whether the rendered page is page1 or page2 or page3. I tried tapping on the white dots but wasn’t able to switch among page views. Could it be a touchscreen (portrait orientation) xinput issue ?

[sharkbait]

@MMRIZE I’ve removed the position of the “MMM-CustomInjection” module from the config.js as per your kind advice. The 3 buttons [prev], [current ] and [next] are still not appearing in the Calendar HeaderTitle (i.e. in my case -> DECEMBER 2024).

This settings for my config.js are as follows:

...,
		{
		  module: "MMM-CalendarExt3",
		  position: "bottom_bar",
		  title: "Our Family Calendar",
		  config: {
			mode: "month",
			cellDateOptions: { day: 'numeric' }, // suppress month from appear in cellDate
			monthIndex: 0, //0=curr_month, -1=prev, 1=next
			instanceId: "basicCalendar",
			maxEventLines: {0:6, 6:5}, // Dynamically sized; 5 events for months with 6 weeks. 6 events for all others.
			firstDayOfWeek: 0,
			calendarSet: [],
			fontSize: '18px',
		  }
		},

		{
			module: "MMM-CustomInjection",
		}, ...

The code deployed for the MMM-CustomInjection.js was:

/* modules/MMM-CustomInjection/MMM-CustomInjection.js */
Module.register("MMM-CustomInjection", {
  getStyles: function () {
    return [
      this.file("MMM-CustomInjection.css")
    ]
  },

  notificationReceived: function (notification, payload, sender) {
    if (notification === "CX3_DOM_UPDATED") {
      const { instanceId } = payload
      this.inject(instanceId)
    }
  },

  inject: function (instanceId) {
    const moduleDom = document.querySelector(`#${instanceId}`)
    if (!moduleDom) return
    moduleDom.classList.add('custom-injected')
    const buttons = document.createElement('div')
    buttons.className = 'calendar-header-buttons'
    const prev = document.createElement('button')
    prev.className = 'calendar-header-button'
    prev.innerHTML = 'PREV'
    prev.onclick = () => {
      this.sendNotification('CX3_GET_CONFIG', {
        callback: (currentConfig) => {
          this.sendNotification('CX3_SET_CONFIG', {
            monthIndex: currentConfig.monthIndex - 1,
          })
        }
      })
    }
    const current = document.createElement('button')
    current.className = 'calendar-header-button'
    current.innerHTML = 'CURRENT'
    current.onclick = () => {
      this.sendNotification('CX3_RESET', {})
    }
    const next = document.createElement('button')
    next.className = 'calendar-header-button'
    next.innerHTML = 'NEXT'
    next.onclick = () => {
      this.sendNotification('CX3_GET_CONFIG', {
        callback: (currentConfig) => {
          this.sendNotification('CX3_SET_CONFIG', {
            monthIndex: currentConfig.monthIndex + 1,
          })
        }
      })
    }
    buttons.appendChild(prev)
    buttons.appendChild(current)
    buttons.appendChild(next)
    moduleDom.appendChild(buttons)
  }
})

The accompanying “MMM-CustomInjection.css” settings were:

/* modules/MMM-CustomInjection/MMM-CustomInjection.css */
.custom-injected {
  position: relative;

  .calendar-header-buttons {
    position: absolute;
    top: 30px;
    right: 0;
    display: flex;
    flex-direction: row;
    justify-content: space-between;
    gap: 10px;
    width: fit-content;

    .calendar-header-button {
      background-color: transparent;
      border: none;
      color: white;
      font-weight: bold;
    }
  }
}

@sharkbait said in Query on MMM-CalendarExt3 modification:

A white circular dot at the bottom indicates whether the rendered page is page1 or page2 or page3. I tried tapping on the white dots but wasn’t able to switch among page views. Could it be a touchscreen

I don’t know… but we can find out pretty easily , using the developers window…

start mm
using the keyboard on the MM screen, open the developers window, ctrl-shift-i
(or use npm start dev to open from the commandline, don’t use pm2)
select the elements tab and then click the arrow on top left

then click one of the circles…
that should open the document view with the buttons selected

you can expand the sections to show the buttons (<a)

now select the sources tab, expand modules in left nav, select MMM-PageIndicator, select MMM-PagIndicator.js, its source should appear in the right pane

scroll down and click on the number on line 66, it should highlight, like this

now click one of the page indicator buttons… mouse or finger

it should show and stop on the line 66 instruction

if it did then it is operating
if it didn’t… hmm…

if it stopped, click the line 66 again , and the highlight will be removed, and then push the blue arrow on the top right, to continue the application

I will test on my touch screen laptop, no expectation that it will fail.
mm is just a page in a browser… nothing special.(from an OS perspective)

edit: tested on my laptop, worked with mouse and touch as expected
edit: ctrl-shift-i to close the developer window
