调整组框内的项目大小 [英] Resizing items inside group box

问题描述

HI, i have one group box inside that i haveseveral elements(some CEdit and CButton)
when i am resizing my window group box is resizing and i want to inside controls also should expand / shrink within the group boxes.
for resizing controls inside group box i have written below logic:

我尝试过：

What I have tried:

RepositionControls(CRect& boundingRect)
{
    m_rGroupBox.MoveWindow(boundingRect, TRUE);
    CEdit* rEditPosRightToLeft[] = { &m_rPrefixEdit, &m_rpszFolderpath, &m_rMaxsizectl, &m_rLifetimectl };
    CButton* rButtonPosRightToLeft[] = { &m_rBtnSelect };
    for (size_t z = 0; z < (sizeof(rButtonPosRightToLeft) / sizeof(CButton*)); ++z) {
        CRect rectChildWindow;
        CButton& ctlButton(*rButtonPosRightToLeft[z]);
        ctlButton.GetWindowRect(&rectChildWindow);
        m_rLogStreamResizer.FetchTabDialog().ScreenToClient(&rectChildWindow);
        int nBtnWidth = rectChildWindow.Width();
        int nBtnHeight = rectChildWindow.Height();
        int bx = m_nSideButtonX;
        int by = rectChildWindow.top;
        ctlButton.MoveWindow(bx, by, nBtnWidth, nBtnHeight, TRUE);       
    }
    /*  TODO: need to implement for the  edit controls*/
    for (size_t z = 0; z < (sizeof(rEditPosRightToLeft) / sizeof(CEdit*)); ++z) {
        CRect rectChildWindow;
        CEdit& ctlButton(*rEditPosRightToLeft[z]);
        ctlButton.GetWindowRect(&rectChildWindow);
        m_rLogStreamResizer.FetchTabDialog().ScreenToClient(&rectChildWindow);
        int nBtnWidth = rectChildWindow.Width();
        int nBtnHeight = rectChildWindow.Height();
        int bx = m_nSideButtonX;
        int by = rectChildWindow.top;
        ctlButton.MoveWindow(bx, by, nBtnWidth, nBtnHeight, TRUE);
    }

以上代码中的CButton逻辑工作正常但CEdit控件无法工作在ECC控件中我有宽度编辑控件取决于调整大小

你能帮我吗

in above code for CButton logic its working fine but for CEdit controls not working inCEdit control i have chage the width of the edit control depends on resizing
could you please help me here

推荐答案

你必须根据可用的宽度来计算宽度，控件的数量，以及控件和边框之间的间距。



假设边框有左右空间，控件之间有空格单个控件的宽度可以计算为：

You have to calculate the width according to the available width, the number of controls, and the spacing between the controls and to the borders.

Assuming you have a left and right space to the borders and a space between the controls the width of a single control can be calculated as:

int availWidth = boundingRect.Width();
int numControls = sizeof(rEditPosRightToLeft) / sizeof(rEditPosRightToLeft[0]);
const int borderSpace = 2; // or whatever you want
const int betweenSpace = 4;
int controlWidth = (availWidth - 2 * borderSpace - (numControls - 1) * betweenSpace) / numControls;

您还必须计算每个控件的左侧位置。它从 borderSpace 开始，并且每次循环迭代必须以 controlWidth + betweenSpace 递增。如果上面的 controlWidth 计算得到最终除法的余数，你也可以得到它并在计算 x 职位。

You have also to calculate the left position for each control. It starts at borderSpace and must be incremented by controlWidth + betweenSpace with each loop iteration. If the above controlWidth calculation has a remainder from the final division, you might also get that and use it up while calculating the x positions.
