Picturebox有时不会显示图像

问题描述

我创建了简单的漫画阅读器，其中包含多个PictureBox，每个页面都包含图像。 PictureBox然后从上到下添加到flowlayoutpanel。

问题是有一些图像没有显示，当我调整图像显示的形式时。





imglayout = FlowLayoutPanel



我的尝试：

i have create simple manga reader with multiple PictureBox to contain image each page. The PictureBox then added to flowlayoutpanel top to bottom.
The Problem is there's some image that doesnt show and when i resize the form the image showed.
Screenshoot to help

imglayout = FlowLayoutPanel

What I have tried:

chapterList.AddRange(Directory.GetDirectories("Gosu"));
            chapterList.Sort(new NumComparer());
            //load chapter pertama
            //simpan image di ram
            foreach (string item in Directory.GetFiles(chapterList[numChapter]))
            {
                imgList.Add(item);
            }
            imgList.Sort(new NumComparer());
            //buat picturebox
            this.SuspendLayout();
            foreach (string i in imgList)
            {
                Image img = Image.FromFile(i);
                PictureBox box = new PictureBox();
                box.Width = img.Width;
                box.Height = img.Height;
                box.BorderStyle = BorderStyle.FixedSingle;
                box.Image = img;
                if (boxwidth < img.Width) { boxwidth = img.Width; }
                imgLayout.Controls.Add(box);
            }
            this.Width = boxwidth+300;
            this.MinimumSize = new Size(boxwidth+300, 550);

推荐答案

private void ShowAlbum(Image[] thumbnails) {
  List<PictureBox> pictureBoxList = new List<PictureBox>();
  foreach (Image img in thumbnails) {
    PictureBox box = new PictureBox();
    box.Image = img;
    pictureBoxList.Add(box);
  }

  flowPanel.Hide();
  flowPanel.Controls.AddRange(pictureBoxList.ToArray());
  // pbox handles are created when the container control is reshown
  flowPanel.Show();
}
