面板之間的靜態距離

Question

我有一個動態創建的N個面板，它們之間的距離為15px

panel.Location = new Point (x, y);  
y = panel.Bottom + 15;

我可以使寬度變小，因此我需要面板之間的高度距離始終為15px。我有一種方法可以對尺寸進行不同的檢查，我嘗試更改距離，但是它的工作原理總是不同的...

public void checkResize(string msg_out, object panel_sender, object text_msg_sender, int panHei, int numbs)
{
    Panel pan_item = (Panel)panel_sender;
    Label lab_item = (Label)text_msg_sender;
    char[] msg_arr = msg_out.ToCharArray();
    int panWidRaz = 308 - pan_item.Width;
    int panWidw = pan_item.Width;
    if (int.Parse(pan_item.Name) != numbs - 1)
    {
        if (panWidw < buff)
        {
            /* if (panWidRaz % 15 == 0)
            {
                for (int i = int.Parse(pan_item.Name); i >= 0; i--)
                {
                    panel1.Controls[i.ToString()].Location = new Point(panel1.Controls[i.ToString()].Location.X, panel1.Controls[i.ToString()].Location.Y + 1);
                }
            }*/
        //width control becomes smaller panels are becoming more in height, it is necessary that the distance between the panels remained 15px
        }
        if (panWidw > buff)
        {
            /*if (panWidRaz % 15 == 0)
            {
                for (int i = int.Parse(pan_item.Name); i >= 0; i--)
                {
                    panel1.Controls[i.ToString()].Location = new Point(panel1.Controls[i.ToString()].Location.X, panel1.Controls[i.ToString()].Location.Y - 1);
                }
            }*/
        //width control becomes bigger panels are becoming less in height, it is necessary that the distance between the panels remained 15px
        }
        buffCountPan++;
        if (buffCountPan == panel1.Controls.Count - 1)
        {
            buff = panWidw;
            buffCountPan = 0;
        }

        if (msg_arr.Length > 26)
        {
            int panWid = (308 - pan_item.Width) / 5;
            int panWidLab = 308 - pan_item.Width;
            pan_item.Height = panHei + panWid;
            lab_item.MaximumSize = new System.Drawing.Size(300 - panWidLab, 100);
            lab_item.MinimumSize = new System.Drawing.Size(300 - panWidLab, 14);
        }
    } 
}

如果您想使其簡單，則當您添加這些面板時，我認為它是動態完成的。 您可以設置panel.tag =“ [Order]”。 所以分配一個訂單號，這樣您就知道哪個是第一個，第二個並繼續...

Const int MinimumStartLocation = 0;
Const int DistanceBetweenPanel = 15;

private void setPanelLocation(Panel pnl)
{
    // retreive the order of this panel
    int iPanelOrder = Convert.ToInt32(pnl.Tag);

    // the first panel must show on top and have specific location
    if(iPanelOrder == 0)
    {
         pnl.Top = MinimumStartLocation;
    }
    else
    {
         // set the top of the panel to the bottom value of the panel just before him in the order plus the constant
         pnl.Top = this.Controls.OfType<Panel>().ToList().Find(pan => Convert.ToInt32(pan.Tag) == iPanelOrder -1).Bottom + DistanceBetweenPanel;
    }
}

現在使用此LINQ命令，它將以正確的順序為每個面板調用上述方法。

this.Controls.OfType<Panel>().OrderBy(x => Convert.ToInt32(x.Tag)).ToList().ForEach(pan => setPanelLocation(pan));

也許值得一看“ 流程布局面板” 。 將控件添加到流布局面板時，它將自動定位到該流布局面板中任何現有控件的左側，右側，頂部或底部（取決於您指定的布局方向屬性）。

同樣，如果您刪除或調整流布局面板中包含的控件的大小，控件的位置將自動為您更新。

在您的情況下，這就像將一個新的流程布局面板添加到表單一樣簡單，然后，對於您添加到流程布局面板的每個面板，將頂部邊距設置為15px，將底部邊距設置為0px； 流程布局面板將負責其余的工作。 當添加，刪除面板或調整面板大小時，流布局面板將確保它們仍然正確顯示，並且它們之間的邊距為15px。
