【中文标题】如何在电子的自定义标题栏中显示/隐藏最大化/最小化按钮【英文标题】:how to show/hide maximize/minimize button in custom titlebar in electron 【发布时间】:2020-10-02 06:03:29 【问题描述】:到目前为止,我在 electron 中制作了一个自定义标题栏(使用 angular 9),分别将这些按钮添加到 html 和单击事件中,以最小化、最大化、恢复或关闭窗口。现在,当用户双击标题栏(因为 css 属性设置为-webkit-app-region: drag
)或用户使用窗口捕捉功能最大化窗口时,就会出现问题。对于,双击我想在角度使用 dblclick 事件但仍然失败。那么,我该如何解决这个问题呢?
titlebar.component.html
<div class="titlebar" *ngIf="showTitleBar" (dblclick)="dblFunction()">
<div class="navigation">
<a class="normal-button material-icons" *ngIf="showBackButton">arrow_back</a>
<div class="appTitle">title</div>
</div>
<div class="wincontrol">
<a class="normal-button material-icons" (click)="minimize()">remove</a>
<a class="normal-button material-icons" *ngIf="showMaxButton ; else showResButton" (click)="maximize()">crop_square</a>
<ng-template #showResButton>
<a class="normal-button material-icons" id="restore" (click)="restore()">flip_to_front</a>
</ng-template>
<a class="close-button material-icons" (click)="close()">clear</a>
</div>
</div>
titlebar.component.ts
import Component, OnInit from '@angular/core';
import WindowService from 'src/app/services/window.service';
import ElectronhelperService from 'src/app/services/electronhelper.service';
@Component(
selector: 'app-titlebar',
templateUrl: './titlebar.component.html',
styleUrls: ['./titlebar.component.scss']
)
export class TitlebarComponent implements OnInit
title = 'Electron-App' ;
showMaxButton ;
showTitleBar = true ;
showBackButton = false ;
constructor(private win: WindowService, private helper: ElectronhelperService)
this.showMaxButton = !this.win.winSettings.wasMaximized ;
ngOnInit(): void
minimize()
this.win.sendMinimize() ;
maximize()
this.showMaxButton = !this.showMaxButton ;
this.win.sendMaximize() ;
restore()
this.showMaxButton = !this.showMaxButton ;
this.win.sendRestore() ;
close()
this.win.sendClose() ;
dblFunction()
console.log('dbl clicked')
this.showMaxButton = !this.showMaxButton ;

【参考方案1】:所以最后在浏览了整个互联网之后,由于区域在 Angular 代码之外运行而导致问题。
titlebar.component.ts
import Component, OnInit, NgZone from '@angular/core';
import WindowService from 'src/app/services/window.service';
import ElectronhelperService from 'src/app/services/electronhelper.service';
@Component(
selector: 'app-titlebar',
templateUrl: './titlebar.component.html',
styleUrls: ['./titlebar.component.scss']
)
export class TitlebarComponent implements OnInit
title = 'Electron-App' ;
showMaxButton ;
showTitleBar = true ;
showBackButton = false ;
constructor(private win: WindowService, private helper: ElectronhelperService, private zone: NgZone)
this.showMaxButton = !this.win.winSettings.wasMaximized ;
this.helper.win.on('maximize', this.toggleMaxButton.bind(this)) ;
this.helper.win.on('unmaximize', this.toggleMaxButton.bind(this)) ;
ngOnInit(): void
minimize()
this.helper.win.minimize() ;
maximize()
this.helper.win.maximize() ;
restore()
this.helper.win.unmaximize() ;
close()
this.helper.win.close() ;
toggleMaxButton()
this.zone.runTask(() =>
if (this.helper.win.isMaximized())
this.showMaxButton = false ;
else
this.showMaxButton = true ;
console.log(this.showMaxButton)
) ;
因为,win.on
事件是异步的,所以需要 ngZone 来切换 angular 内的布尔值。解决这个问题确实花了一周的时间!
