Toggles a state variable to either visible or hidden which is used to set a related class on the toolbar. The hiding is done with CSS, just reducing the width of the toolbar and the opacity of the tools.
All zoom buttons run through same handler now.
They no longer take only the delta of the current zoom and desired zoom-- they take the actual desired zoom.
calculateZoom is now calculateChange, to help get the desired delta.
Removes icons as components, uses mask-image instead.
Sets a size on the .fac icons to 1em so by default they are 1em and retain their aspect ratio.
rename the icon files for consistency.
Reintroducing handlePageChange() method to handle the page input separately from the scroll function. It tests the regex pattern on the string, parses to integer, and sets pageNum state.
scrollToPage also now sets the pageNum state after performing the scroll so the input box matches the new current page.
stylelint has a problem with the `:horizontal` pseudo selector in brewRenderer.jsx, which is being used to apply some styling to the custom scrollbars. As far as i can tell, the selector is not standards-track, so that is probably why. Not sure if we want to adjsut our stylelint config to allow it?
Moved the single-line handler to operate directly in the onChange handler of the input that is calling it.
Considered doing the same with handleZoomChange, but that handler is used by two buttons rather than just one.
New icons for Zoom to Fit, and Fit Width buttons. Used SVGR online tool to create react components and then combined them.
If doing in future, be sure to set currentColor on `fill` property in the SVG itself. Make the SVGs as closed curves only (don't rely on stroke). set only a width property, not height.
Reduce overlap of the two functions and just require a 'mode' parameter. Could like roll a 'manual' mode into this for the zoom slider, as well, but skipping for now.
Adds a toFit() method to determine the delta/change needed to the current zoomLevel to fit the page to the pane, so that the widest page fits just inside the pane.
Treat each input and button as a direct child of the `.group` class, removing the intermediate div and reassign the `tool` classname to those inputs and buttons. One item, the current / total page "set", is wrapped in a .tool div because they should be considered one item (even within the .group container).
And then a bunch of CSS adjustments to match the new structure.
Make it so that if a user enters a page number higher than the total page count, it jumps them to last page. if lower than 1, it jumps them to first page.
Displaying the total page count near the current page number means we can lose the bottom right toolbar entirely (the renderer could be added to top toolbar, or just left for the metadata info in title bar).
putting the `pageInput - 1` modifier in the `scrollToPage` method allows for more understandable button function ('back button' is `- 1` and 'forward button' is `+ 1`).
Changing input type to text removes the "spinner" controls from within the text box. The spinner buttons are an accessibility issue (the tiny buttons are tiny), and we already have better buttons for incrementing/decrementing page number.
Text box only accepts numbers.
Moved onChange handler function to a component method and simplified it a smidge.
Must use parseInt now because the input type will change to 'text' rather than 'number'
totalPages shouldn't need to be in state, since this component won't be changing it.
renamed pageNumberInput to just pageInput. Was just something that happened in the course of working on it.
currentPage doesn't need to have it's own state separate from pageInput, they should always be the same *value*.
Set as relative position, the toolbar (and mysteriously, the pageInfo box) would jump up 29px (toolbar height) when the "next page" button was clicked. absolute pos fixes this.
Moved the zoomLevel state assignment to a newer useState hook function, making it easier (and shorter) to update that state within event handlers.
The slider onChange is a single easy line, and the buttons handlers are two lines for clarity.
